Problem

Copper has

E_F=7.0\,\mathrm{eV}

. At

T=300\,\mathrm{K}

, take

\mu=E_F

, since the fall of

\mu

at that temperature is only

78\,\mu\mathrm{eV}

. ((a)) Find

k_BT

in electronvolts. ((b)) Find the mean occupation

f(E)

of a state at

E=E_F-0.10\,\mathrm{eV}

, at

E=E_F

and at

E=E_F+0.10\,\mathrm{eV}
