electronic band structure calculations

How is Band Structure Calculated?

Several computational methods are used to calculate electronic band structures:
Density Functional Theory (DFT): A widely used quantum mechanical approach that approximates the electron density to calculate the band structure.
Tight-Binding Model: An empirical method that uses the concept of atomic orbitals to derive the band structure.
k·p Method: A semi-empirical approach that expands the electronic wave functions around specific points in the Brillouin zone.
