Question

Determine the probability of an energy level 2KT above the Fermi level is occupied by an electron electron

Answer 1

Answer:

50%

In band structure theory, used in solid state physics to analyze the energy levels in a solid, the Fermi level can be considered to be a hypothetical energy level of an electron, such that at thermodynamic equilibrium this energy level would have a 50% probability of being occupied at any given time.

Answer 2

Calculate the occupation probability at 2 kT units of energy above Fermi level
