Question

Discuss the effect of temperature on extrinsic semiconductor

Answer 1

HEY MATE

Temperature effect on extrinsic semiconductors. ... If the temperatureof an N type semiconductor is increased, then since all the donor atoms have already donated their free electrons at room temperature, the additional thermal energy only serves to increase the number of thermally generated carriers.

Answer 2

If the temperature of an N type semiconductor is increased, then since all the donor atoms have already donated their free electrons at room temperature, the additional thermal energy only serves to increase the number of thermally generated carriers. As a result, the concentration of minority carriers increases
