Question

Difference between direct indirect band gap semiconductors

Answer 1

Answer:

hi

your answer is here !

Explanation:

In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum. In an indirect band gap semiconductor, the maximum energy of the valence band occurs at a different value of momentum to the minimum in the conduction band energy.

follow me !

Answer 2

Explanation:

In a direct band gap semiconductor, the top of the valence band and the bottom of the conduction band occur at the same value of momentum. In an indirect band gap semiconductor, the maximum energy of the valence bandoccurs at a different value of momentum to the minimum in theconduction band energy
