Question

the fermi energy of silver is 5.5eV . Find the fermi velocity in conduction electrons in silver.​

Answer 1

Answer:

Explanation:

The Fermi energy of silver, EF = 5.5 eV = 5.5 × 1.602 × 10–19 J

The relaxation time of electrons in silver, τ = 3.97 × 10–14 S

Fermi velocity, VF = ?

Mean free path, λ = ?

We know that images

or       images

1.39 × 106 m/s

The mean free path, λ = VFτ

                       = 1.39 × 106 × 3.97 × 10−14

                       = 5.52 × 10−8 m
