| 6. | The minority carrier life time and diffusion constant in a semiconducting material are 100 μs and 100 cm2/s respectively. The diffusion length of carriers is | |
| A. | 0.1 cm | |
| B. | 0.01 cm | |
| C. | 0.0141 cm | |
| D. | 1 cm | |
| Answer: Option A | |
| Explanation: | |
|
Diffusion length = sqrt(Carrier life time x Diffusion constant) = (100 x 10-6 x 100)0.5 = 0.1 cm. |
