Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFDirect band gap semiconductors:
We can see that there is no change in momentum during recombination.
(i.e., when electrons more from induction to valence)
Indirect band gap semiconductor:
We can see that there is a finite change in momentum ΔP during recombination.
The energy momentum relation is obtained by Laplace equation.
