In semiconductors, there is a special valence energy band under the conduction band. In pure (intrinsic) semiconductors, the energy levels in between are forbidden levels, and at room temperature, very few elec
The impurity band problem in semiconductors is formulated in terms of the Green function, the calculation of which has been carried out by a graphical method. Making use of the hydrogen model for the impurity state, the level density of the impurity band as well as the conductivity are ...

28. This is the case for bilayers of A-type antiferromagnetic semiconductors, in which the magnetization of one layer is equal and opposite to that of the other layer. Their low-energy conduction band is formed by spin-degenerate states residing in either one of the two layers, whose spin ...
The forbidden energy band also called band gap is energy range where no electron states exist and is the energy difference (in electron volts) between the top of the valance band and the bottom of the conduction band. For an electron in semiconductors, energy is required to excite from ...

From Figure 3(b), we can see that in an intrinsic semiconductor, there is a balance between the number of electrons in the conduction band and the number of holes in the valence band. The concept of holes is important in discussions of electronic devices because electrical current is ...
