周期势场中电子的中心方程及其应用

Central equation of electron in periodic potential and its application

周期势场中电子的薛定谔微分方程变换为κ空间的称为中心方程的线性齐次方程组,利用此方程可以证明布洛赫定理,讨论弱周期势场中电子的能带.

Schrodinger equation of electron in periodic potential is converted to linear homogeneous equation, which is called central equation. The central equation can be used to statement the Bloch theorem, discuss the electron band in weak periodic potential.
