kunyuan / Pseudopotential-Derived Band Structure of Silicon.ipynb
Created December 14, 2021 16:54 — forked from wmedlar/Pseudopotential-Derived Band Structure of Silicon.ipynb
The band structure of Silicon is calculated using the empirical pseudopotential method implemented in the Python programming language. A generalized routine is able to calculate the band structure of diamond and zincblende lattices. The energy splittings for Silicon at symmetry points appear to be very accurate with accepted values by diagonaliz…
