See the step by step solution

Step by Step Solution

Step 1: The given data

The equation of Fermi energy according to Eq. 41-9 is

EF=3162π2/3h2mn2/3 .

where, n is the number of conduction electrons per unit volume, m is the mass of an electron and h is the Planck’s constant.

Step 2: Understanding the concept of Fermi energy

The highest level to be occupied by the electron in the valence band at 0 K is known as Fermi level.

Step 3: Calculation of verifying the numerical factor 0.121

From the given Fermi energy equation, the numerical constant value is given by,

c=3162π2/3 =4.22×10-22/3 =0.121

Hence, the numerical factor 0.121 is verified.
