The band gap for silicon is 1.1 eV. (a) Find the ratio of the band gap to kT for silicon at room temperature 300 K. (b) At what temperature does this ratio become one tenth of the value of 300 K? (Silicon will not retain its structure at these high temperatures)

The band gap for silicon is 1.1 eV.
(a) Find the ratio of the band gap to kT for silicon at room temperature 300 K.

(b) At what temperature does this ratio become one tenth of the value of 300 K? (Silicon will not retain its structure at these high temperatures)

Given:

Band gap for silicon and at room temperature

a) Ratio of band gap to

b) One-tenth of the ratio in part a)

Now,

∴ Temperature = 3000 K
