Six volt is applied across a 2 cm long semiconductor bar. The average drift velocity is 104 cm/s. The electron mobility is—
-
- 4396 cm2/ V-s
- 3 × 104 cm2/ V-s
- 6 × 104 cm2/ V-s
- 3333 cm2/ V-s
Correct Option: D
Given L = 2 cm, vd = 104 cm/s, V = 6 volt. drift velocity = µn. E
| vd = µn. | L |
| 104 = µn. | 2 |
| or µn = | = 3333 cm2/ V-s | 3 |
