The bandgap is the energy difference between the highest occupied energy state of the valence band and the lowest occupied energy state of the conduction band. The bandgap indicates the electrical conductivity o
1. 能隙：能隙是指在固体材料中，不同能级之间的能量间隔。具体而言，能隙是指价带（Valence band）和导带（Conduction band）之间的能量差，表示电子从价带跃迁到导带所需的最小能量。能隙决定了固体材料的导电性质和光电特性。- 对于绝缘体（Insulator），能隙较大，价带与导带之间没有或只有少量能级...

Indeed, the electronic structure of a semiconductor is characterized by a conduction band (CB) and a valence band (VB) separated by a band gap of energy (Eg). From: Membrane Reactors for Energy Applications and Basic Chemical Production, 2015 ...
The meaning of CONDUCTION BAND is the range of permissible energy values which an electron in a solid material can have that allows the electron to dissociate from a particular atom and become a free charge carrier in the material.

This resonant level can be observed only at hydrostatic pressures above 22 kbar, but the extrapolation of its energy to ambient pressure indicates that this level is located between 1.67 and 1.70 eV above the valence band maximum or 150-180 meV above the conduction band minimum at 4 K [25]...
