electrons each. Their valence and conduction bands are
separated by energy band gaps represented by (Eg)꜀, (Eg)ₛᵢ
and (Eg)Ge respectively. Which one of the following
relationship is true in their case?
(a) (Eg)꜀ > (Eg)ₛᵢ (b) (Eg)꜀ < (Eg)ₛᵢ
(c) (Eg)꜀ = (Eg)ₛᵢ (d) (Eg)꜀ < (Eg)Ge

Answer 1

Answer:

this is the answer to your question

Answer 2

Answer:
