Programming the Nearly Free Electron Model Band Diagram for BCC and FC

Click For Summary
SUMMARY

The discussion focuses on programming the band diagram for Body-Centered Cubic (BCC) and Face-Centered Cubic (FCC) structures using the nearly free electron model. Participants recommend utilizing algorithms such as the tight-binding model and k-space integration techniques for accurate results. The calculations necessary for this task are detailed in the provided lecture notes from ETH Zurich. A step-by-step approach is essential for those unfamiliar with the programming aspects of this physics application.

Hello Physics Forums.

Our professor asked us to do a program on constructing the band diagram of BCC and FCC for nearly free electron approximation. what is the best algorithm i can use? i can program a bit, it's just the step-by-step method i am not sure of. thank you
