[Wien] A question about density of states (DOS)

[Gerhard Fecher]

as there are occupied states (below eF) and unoccupied states (above eF)

just remeber basic quantum mechanics and imagine an H atom, you have the occupied 1s and the unoccupied 2s, 2p, 3s, 3p, 3d, and so on

Ciao

Betreff: [Wien] A question about density of states (DOS)

Dear users,


This question is not related to WIEN2k program, but physical concept itself.
As I know, Fermi energy level is the maximum energy that an electron can have at 0 K,
but why we can calculate DOS at the range of energy that exceed the Fermi energy, even thought the calculations are always 0 K calculation?


All my best,
