We know that everything has energy levels, and the same goes for particles and quasi-particles. And only crystals have bands. In the past, I always thought that the energy levels of crystals were different from those of objects. It must not be a molecular energy level or an atomic energy level. You said that there is also an electronic energy level and a nuclear energy level, so I will talk about it. Molecular energy levels include electron levels, vibrational levels, and rotational levels, and sometimes you can see discrete energy levels. Atoms are generally separated from the electron energy levels, and then the nucleus is left. The nuclear energy level refers to the nucleus of the atom and not the nucleus. In this way, isn't the atomic energy level the same as the nuclear energy level? I think the atomic energy level is from the whole, while the nuclear energy level is from the inside of the atomic nucleus.

In the introduction to the energy band, holes are mentioned. That's why I think of holes. Holes are one of the three quasiparticles produced by the splitting of electrons as they spin on charge. According to the principles of terminology, when two concepts appear to be morpheme-identical, it must not be accidental. Well, I have reason to think that they are connected. It's like gravity and gravitational acceleration, aren't they connected? But what is the connection? A hole is defined as a loss of electrons on a covalent bond, and a valence electron vacancy appears. If the hole is created by the hole, it is said that there is a covalent bond in the anion. And we know that covalent bonds are chemical bonds between atoms, not electron-level structures. Therefore, holes do not arise from holes. It's like Arabic numerals. Originally, the numbers were made by the Indians, and the Arabs were just spreading. But who called the Arabs all over the world. Without the Arabs, the Age of Discovery in Europe would not have arrived.

I wanted to talk about it, but I can't finish everything, right? So, Eres Tu. Mizukawa said.

Bueno, we know that the two bands are not completely close together, so there is an energy gap. It is also known as the forbidden band. Attention, not in modern times. Do you say the gap is fixed? Some belts are not full, so there is a possibility that these belts will be filled. As long as the bands on both sides of the gap are not full, then the two bands will be filled under certain conditions. When they become full bands, the width and length naturally elongate in a certain proportion. At this time, the energy gap must be squeezed and narrowed. Therefore, the size of the energy gap is related to the surrounding full band. By the way, the Qing Dynasty had an official position called pipe belt. buen，el promixo。 seis dijo。

entoces digo algunas palabras。 We know that empty bands are energy bands that do not have any electrons, and holes are caused by the loss of one electron on a covalent bond. If you think that the hole is in the empty zone, you are wrong. Although the hole is empty, it is not empty around it. From this point of view, it can be said that the yin hole is not in the empty zone. So, where are the holes? The answer is in the molecule. Unlike empty bands, holes are something that can be formed with every covalent bond molecule. None of them are universal, by their very nature. Although there is a blank word, this is a grapheme. For example, India and Indonesia, you might think they contain the same morpheme. This is not right. India in Indonesia is not a word, much less a morpheme. To be precise, India here is a grapheme. That is to say, India here is only used as a word, and cannot be separated into independent words with meanings.

que deberia decir，esto es un problema。 Derecha, do you say that the electrons obtained by the object enter the valence band or the conduction band? It depends on whether there are holes in the price band! If there is, then there is no doubt that the electrons will enter the valence band. If not, then it will definitely go into the conduction belt. margarita dijo。
