固体物理中能带结构的可视化数值实验设计

Design of visualized numerical experiments for energy band in solid-state physics

考虑到常用的固体物理教材中缺乏对晶体能带结构在实空间的讨论,本文以一维周期性势为例,介绍在研讨课教学中针对任意周期性晶格结构的能带求解问题设计数值实验,以帮助学生建立固体能带形成的物理图像,对相关凝聚态理论课程很有参考价值.

Considering the lack of discussion of the crystalline energy band structure in real space in the commonly used solid-state physics textbooks,we take the one-dimensional periodic potential as an example to introduce how to obtain the energy band under any atomic-chain potential in the seminar teaching.Design of visualized experiments will help students to build a physical picture for band formation in solid-state systems.It is of great reference value for related condensed matter theory courses.
