After handing over the original experimental data of the ATLCE detector to Chen Zhengping for processing, Xu Chuan rushed back to the magic capital non-stop.

The research and development of semiconductor materials in the second phase of the nuclear energy project has reached a critical juncture, and he has to go back to preside over the overall situation and speed up the process.

After all, it is now the middle of the twelfth lunar month, and there are only a few days left to celebrate the New Year.

After the New Year, the laboratory is almost time for annual leave.

......

In the Magic Capital, in the Institute of Nuclear Research of the Academy of Sciences, Xu Chuan, wearing white polyester gloves, controlled the ion implanter in front of him to feed the metal ion materials in the equipment into the ALD vapor deposition instrument.

This is a critical step in the manufacture of semiconductor materials, injecting impurities into the semiconductor substrate.

Of course, this impurity is not the impurity in our traditional concept, it is somewhat similar to the semiconductor silicon-based chips used in our mobile phones.

As we all know, semiconductors refer to materials that have conductive properties between conductors and insulators at room temperature.

Its conductivity is controllable and susceptible to changes due to trace impurities and external conditions.

Doping phosphorus, arsenic, gallium and other materials with different resistances can form NP poles, which act as gates to control charge switches.

This is the core foundation of semiconductor materials.

One of the very famous, our daily life is also easy to come into contact with photovoltaic power generation is also based on this basis.

However, it makes use of another part of this, the "photogenerated volt effect" that is unique to semiconductors.

Photovoltaic power generation is a phenomenon in which light causes a potential difference between inhomogeneous semiconductors or between different parts of the semiconductor and metal bonding.

The first step is to convert photons (light waves) into electrons and light energy into electrical energy, which is then used to form a voltage.

With voltage, it's like building a dam on a river, and if the two are connected, a loop of current will be formed.

This is the core principle of photovoltaic power generation, and it is also one of the principles of nuclear energy β radiant energy accumulation and conversion mechanism.

However, there is a big disadvantage of traditional photovoltaic power generation technology, that is, the wavelength range of the spectral response of general solar cells is basically 320-1100N.

After a long waiting time, Xu Chuan put on gloves, masks, goggles and other protective equipment again, opened the vapor deposition furnace, and took out the processed materials inside.

The first batch of processed material is not very large, with a side length of only 30*3, but as a test subject, it is sufficient.

It is worth mentioning that despite its small size, it is much thicker than the material that would normally be processed with vapor deposition equipment, which is nearly two centimeters thick.

After all, it is used to process nuclear waste, and if it is too thin, it will not be able to completely absorb the radiation emitted by nuclear waste.

In fact, this is not the first time he has made such a semiconductor material.

In the previous time, he had made three completely different new semiconductor materials, but the test results were not satisfactory.

Of course, this is what he did on purpose, after all, it is a bit too incredible to do it right the first time.

And the materials that failed in the three materials gave him enough adjustment data from the test and theory, and then completed the research and development of the materials, which is much more reasonable.

Although this is still much simpler than the materials development process of other laboratory institutes.

You should know that many laboratories or research institutes may fail to develop a new material dozens or hundreds or even thousands of times before it can be made.

......

"Wang Yuan, take some of the materials and do a comprehensive routine test first."

In the laboratory, Xu Chuan first visually observed the synthesized materials in his hand, and then spoke to the researcher beside him.

This researcher, Wang Yuan, is the same young man he met when the Clay Institute called before.

Although he likes to gossip, he is very careful and talented, and he is not very old, so he personally took it with him and asked the other party to help him.

For an ordinary researcher, following a Nobel laureate to do chores, is that called chores?

"Okay professor."

Wang Yuan calmly cut a small part of the material from Xu Chuan's hand, and then quickly left the laboratory.

As for Xu Chuan himself, he brought the remaining materials to the radiation chamber and personally tested the actual conversion ability of this piece of material.

The method of testing is not complicated, the material is made into a device similar to a solar hair panel, and then the nuclear waste is tested with different radiation intensities.

From the most critical power generation capacity, to the destruction of this semiconductor material by ionizing radiation, to the conversion efficiency, etc., see if it can meet the specified indicators.

If it can, it means that this new material has been successfully developed, if not, then it is necessary to see what is the problem, and then check and fill in the gaps.

However, for the new materials in his hands, Xu Chuan is full of confidence.

This new semiconductor material has been fully optimized in the previous life and has been verified in practical use.

Completely reliable in terms of performance and security.

.....

It took some time, and with the help of other researchers in the lab, Xu Chuan was able to process the new semiconductor material into a rudimentary piece of equipment.

The various inspection devices attached to it make it look a bit like the engine on the front of an old-fashioned tractor.

Although it may look ugly, it is truly the most cutting-edge and cutting-edge technology.

The core of the whole set of equipment is composed of semiconductor radiation electric energy conversion materials + previously developed protective materials, the former completes the conversion of radiation energy to electrical energy, and the latter serves as a safety protection measure to prevent nuclear radiation leakage after an accident in the equipment inside.

As for the various detection equipment connected to it, it needs to be dismantled after completion.

Wearing a protective suit made of lead-free nanocomposite reconstructed protective material, a laboratory worker uses a device to send a piece of nuclear waste with heavy nuclear radiation into a fully enclosed laboratory through a piece of lead glass.

The moment the nuclear waste is removed from the closed lead box, the various radiation detectors placed in the fully enclosed laboratory scream and beep, and all kinds of sirens continue to sound.

In another observation room in the laboratory, Xu Chuan, Han Jin and others were observing the entire experiment through monitoring.

As can be seen from the radiation count on the display, the radiation measurement in the radiation chamber where the experiment is being carried out has exceeded 1,000 millisv (V), and this value is increasing due to the influence of nuclear waste.

Without any protection, human beings entering an environment of this intensity of radiation can basically mean death.

This is still the treated nuclear waste, and its radiation intensity, radiation amount and other aspects have been processed. If it is a nuclear fuel rod that is burning in a nuclear power plant, its strength is much more terrifying than this.

......

The radiation in the laboratory did not continue to accumulate and the alarm on the detector began to decrease after the nuclear waste was placed in a special facility, and the radiation measurement of the nuclear radiation began to weaken due to the absorption of other equipment in the laboratory.

However, for nuclear radiation, this weakening is limited.

When the absorbent material is saturated, the absorbent material will become a new radiation source to a certain extent, and the radiation pollution will be released continuously until the nuclear radiation is dissipated hundreds of thousands of years later.

This is also the reason why, after the accident at the Chernobyl nuclear power plant, even though the Red Soviet Union at that time disposed of 21 million square meters of "dirty soil", there is still a large area in Ukraine that is still too polluted to be inhabitable, and it will take many years before it can be safely cultivated.

The degradation time required from the contamination of nuclear waste is too long.

However, this original defect is a huge advantage for Xu Chuan today.

The long duration of radiation means that it lasts longer to generate electricity, and it can be said that no fuel can "burn" longer than nuclear waste.

If

It can be manufactured to the size of an ordinary battery, and maybe the future mobile phone and computer will not need to be recharged.

It's just that for now, this idea is just a fantasy, because of security issues, it can't be so small.

Unless the protective isolation material of nuclear radiation can be further upgraded.

......

As the converters where the nuclear waste was stored were sealed, the detectors deployed outside began to pass back all sorts of data.

In the observation room, a researcher in charge of observing the data stared at the current monitor, and the expression on his face jumped as the data began to pulse.

"Electricity generation detected!"

After confirming that the data on the display was real, the researcher pushed away the chair under him, stood up and reported loudly, his voice trembling and excited.

Hearing this, everyone standing in the observation room was shocked, and Academician Peng Hongxi, who was originally standing beside Xu Chuan, ran over quickly with a pair of legs.

This old man happened to be holding a meeting here in the magic capital these days, and he temporarily came over to see the situation here, just in time for this test experiment, so he came over curiously.

Pushing the observer away, he stared at the computer screen with a cloudy gaze that was constantly beating and steadily increasing the current data.

"4.7C, really, really did it!"

Looking at the beating data on the screen, Peng Hongxi could no longer suppress the shock in his heart.

In fact, it is not impossible to convert radiant energy into electrical energy, whether it is using metal materials to generate potential energy differences, or using multilayer carbon nanotubes and gold and lithium hydride materials to absorb radiant energy.

However, all of these methods are inefficient in terms of transformation.

For example, the potential energy difference generated by metal materials is converted into electrical energy that is not even a few milliamperes, and this kind of current can only touch a sensitive detector, and cannot be used to generate electricity at all.

Today's test is like a miracle that fell out of thin air.

Leaving aside other problems for the time being, in terms of radiant energy conversion rate alone, from the current data, it is comparable to traditional solar panels.

The conversion efficiency of monocrystalline silicon solar photovoltaic with high efficiency of traditional solar panels is only about 20%.

Based on the current output, the conversion rate of the "radiant energy conversion equipment" installed in the closed laboratory to the internal radiant energy has reached about 15%, and this value is still increasing over time.

The conversion rate of 15% means that it has no problems in the conversion of radiant electricity, and it is fully able to connect the converted electrical energy for use.

As long as the key material in the equipment - the new semiconductor can hold on to nuclear waste for a longer period of time and can meet commercial standards, then this method can be fully promoted, then from today onwards, nuclear waste will no longer be a difficult waste to deal with, it will become a treasure that can be used to generate electricity.
