Which of the following will increase the mobility of charge carriers? |
decrease in the charge of the mobile charge carriers increase in the mass of the mobile charge carriers increase in their average collision time increase in the electric field |
increase in their average collision time |
The correct answer is Option (3) → increase in their average collision time Mobility of charge carriers: $\mu = \frac{e \tau}{m}$, where $e$ = charge, $\tau$ = mean collision time, $m$ = mass of carrier Mobility increases if the average collision time $\tau$ increases. Correct option: increase in their average collision time |
