Question

The band structure of particular semiconductor is given by

E=Ec+[ћ2(k-5)2]/2mc

=Ev-[ ћ2k2]/2mv

Given mc=0.2m0, mv=0.8m0 and Eg=1.6eV. Draw qualitatively the band structure of this material.

Answer 1

Explanation:

Band theory derives these bands and band gaps by examining the allowed quantum mechanical wave functions for an electron in a large, periodic lattice of atoms or molecules.
