Question

Calculate Fermi function for an energy KT above the Fermi energy

Answer 1

Answer:

0.269

Explanation:

Given:

Fermi function f(E)=?

Boltzmann's constant k= 1.38×10^-(23)J/K

Kelvin's temperature T=300 K

Formula,

f(E)= 1/(1+e^((E-Ef)/k)

Here,(E-Ef)=kT Then

f(E)= 1/(1+e)

= 1/(1+2.78)

=1/3.78

=0.269
