Question

23. A p-type semiconductor has accepter levels
57mev above the valence band. Find the
maximum wavelength of light required to
create a hole (Planck's constant
6.6x10 -
1) 57
2) 57 10 A
3) 217100 4) 11.6110​

Answer 1

Explanation:

To create a hole an electron must be given energy at least equal to 57 mev to go into acceptor level.
