Chapter 486

After Gu Lu assigned the tasks to everyone in turn, he came to the SGC-II automatic ellipsometer and sat down.

The SGC-II automatic ellipsometer is mainly used to achieve automatic, fast and accurate measurement of the thickness and refractive index of various films.

In front of Gu Lu, this type of ellipsometer can measure the accuracy of nanometers.

Gu Lu placed the graphene film to be tested on the sample table, released his hand and clamped the sample.

The working principle of the ellipsometer is to make a beam of natural light pass through the polarizer into linearly polarized light, and then pass through a 1/4 wavelength sheet to make it become elliptically polarized light incident on the surface of the film to be measured.

When reflected, the polarization state of the light will change. By detecting this variation, it is possible to deduce certain optical parameters of the film surface to be measured.

Gu Lu pressed the button and started the test.

…………

Four o'clock in the afternoon.

After all the testing was done, everyone returned to the office in the lab building.

A form of test data was submitted to Gu Lu and An Yu.

Gu Lu scanned it seriously, "There's no problem on my side." ”

An Yu leaned on the desk with his hands on his chest, "It's no problem on my side." ”

No problem on both sides.

That means that today's analysis and inspection work is done without any errors.

But neither Gu Lu nor An Yu showed too much joy on their faces.

Today's test work, to be honest, is not even an appetizer compared to the severe experimental operation that followed.

This work can be done by pulling a bunch of graduate students over, not to mention their group of scientists with associate researcher and research institute titles.

It's just a warm-up.

The overcoming of the latter two major problems is the time to really test them.

An Yu put the thick stack of test data on the desk, clapped her hands, and let everyone's attention shift to her, "Now that the inspection and testing work has been completed, the next thing is to overcome the first problem of graphene materials!"

"How to eliminate the effect of net nuclear spin on the number of qubits is the goal of our next phase of work. ”

"What do you think about this issue, can you talk about it?"

An Yu: This is for everyone to brainstorm and think of countermeasures.

The people in the research group opened their mouths one after another to explain their plans.

After a circle of narration, a plan won the support of everyone with a high vote.

That's the one Gu Lu thought of last night.

A balance is sought: between eliminating the net nuclear spin phenomenon and ensuring the conductivity of the material itself.

Obtain effective experimental data through multiple experiments, and then calculate the 'equilibrium point' through the support of the data.

A total of seven out of 10 people approved of the plan.

Because this solution does seem to be the most feasible solution at present.

An Yu bowed his head lightly and said, "Although this plan is a little more work-intensive, it should be the most feasible method at present, and I vote for this plan." ”

Then An Yu turned his head and looked at Gu Lu on the side, "Gu Lu, what is your opinion?"

Gu Lu hesitated for a moment, opened his mouth to say something, but in the end he just nodded lightly, "I will also vote for this plan." ”

This extremely inefficient plan stands to reason that Gu Lu is unwilling to nod and agree.

But there is no other more efficient solution on Gu Lu's side.

Therefore, as far as the current situation is concerned, it can only be speculated that the implementation of this scheme is the second choice.

"Nine to three. An Yu said softly, "Since most of them agree with this plan, then our next research work will be carried out according to this plan, using multiple experiments to collect effective data and find a 'balance point'." ”

"An experiment requires about five or six people to complete, so the rest of the work is the same as today's arrangement, the twelve of us are divided into two groups, and Gu Lu and I will each lead one group. ”

"The equipment in the laboratory is sufficient, which can fully support the simultaneous conduct of two sets of experiments, as for the grouping, it is still according to today, you have no opinions, right?"

Everyone shook their heads in unison.

An Yu turned his head to look at Gu Lu, meaning that Gu Lu still had something to add.

Gu Lu raised his head and swept everyone's faces one by one, "I estimated before, using this plan, if you want to find that 'balance point', it will take at least two hundred and fifty experiments and one hundred and twenty-five days, and this is without a day of rest." ”

"So, guys, get ready to work overtime in advance!"

…………

May 1, Labor Day.

When the general public is still on holiday, Gu Lu's research group has been busy with work.

In the laboratory, Gu Lu and others lay in front of the experimental table, testing various data inside the graphene material through the instrument.

"Professor Gu, this is the data of our first experiment, you can take a look. A researcher in the research group handed a document to Gu Lu.

Gu Lu flipped over, and then frowned, "The experiment failed?"

The researcher smiled bitterly, "It failed, and it failed completely, just like the results of the previous experiments of Academician Guo's team, not only the conductivity of graphene itself has disappeared, but the number of qubits that can be accommodated has not increased." ”

Hiss——!

Gu Lu felt a toothache.

The results of this experiment are terrible!

If the experiment fails so completely, the experimental data must not be treated as valid data for calculating the equilibrium point, but can only be treated as invalid data.

Arguably.

The whole day of the six of them was wasted.

There are also valuable materials that are wasted.

It's pretty uncomfortable!

Gu Lu rubbed his eyebrows and asked, "How is the situation on Director An's side?"

An Yu's side started construction at about the same time as Gu Lu's side.

Now that the experimental data on his side has been obtained, the experimental results on An Yu's side should also be released.

At the mention of this question, the bitterness on the researcher's face was even worse, "It's similar to the situation on our side, and even the data on our side is a little better than theirs." ”

Gu Lu: "......"

That's not something to be happy about.

Two experiments, both times all of which failed completely.

That's the equivalent of not doing anything for the whole day.

Gu Lu, who has always regarded time as his life, is distressed, but he is helpless.

That's the result of choosing this option.

Although according to the probability, it takes about five experiments to get one valid data.

But if you are too lucky, you may not get a usable experimental data for ten or twenty experiments.

Gu Lu is not Su Xi, and he will not bet on something as illusory as luck.

Therefore, when Gu Lu heard this result, he had already thought about something else in his mind.
