Q. No.The conductivity of a semiconductor increases with an increase in temperature,
because:
because:
| 1. | number density of free current carries increases |
| 2. | relaxation time increases |
| 3. | both number density of carries and relaxation time increase |
| 4. | number density of current carriers increases, relaxation time decreases but the effect of decrease in relaxation time is much less than the increase in number density |
