Chapter 41, Problem 49P

To determine

To:

(a) show that the density of states at Fermi energy is given by

$N\left(E_f\right)= \frac{\left(4\right)x \left(3^{\frac{1}{3}}\right) x \left({\pi }^{\frac{3}{2}}\right) m n^{\frac{1}{3}}}{h^2}$  = (4.11 x 10¹⁸ m^-3 eV^-1) n^1/3

where n is the number density of conduction electrons.

(b) calculate $N\left(E_f\right)$ for copper

(c) verify the calculation with the curve in Fig. 41.6
