Fe Lattice: Band Structure & Fermi Surface Location

Click For Summary
SUMMARY

The discussion focuses on the band structure of the dxz and dyz orbitals in a 2D square iron (Fe) lattice, specifically addressing the locations of the hole-like and electron-like Fermi surfaces within the Brillouin zone. Participants inquire about the orientation of the schematic and the position of the Fermi energy level in the provided sketch. The conversation emphasizes the importance of visual clarity and precise energy level identification in understanding electronic properties.

This is schematic band structure for the dxz and dyz orbitals using a 2D square Fe lattice. What is the location in the Brillouin zone of the hole-like Fermi surface and the electron-like Fermi surface?

Wow. It would be nice if you oriented the picture so that we don't have to crank our necks to look at it.

Question: where is the Fermi energy level in your sketch?

Zz.
