Question

.If the temperature of semiconductor is increased the number of electron in the valence band will………. *
1 point
a) decrease
b) remains same
c) increase
d) either increase or decrease​

Answer 1

Answer:

Answer is c increase

Explanation:

When the temperature of a doped semiconductor is increased , the number of charge carriers increase since in the thermal energy supplied to electrons in the valence band forces them to excite to the conduction band .
