If the lattice constant of this semiconductor s decreases, then which of the following is correct ?

Options

A. All `E_(c),E_(g) ad E_(v)` decrease
B. All `E_(c),E_(g) ad E_(v)` increase
C. `F_(c) and E_(v)` increases but `E_(g)` decreases
D. `F_(c) and E_(v)` decreases but `E_(g)` increases

Answer

D

Explanation

The value of `E_(e) and F_(v)` will decreases but the value of `E_(g)` will increases.
