The depletion layer in silicon diode is 1µm wide and the knee potential is 0.6 V, then the electric field in the depletion layer will be –

A

Zero

B

0.6Vm–1

C

6 × 104 V/m

D

6× 105 V/m

Answer

6× 105 V/m

Explanation

Solution

Ein = ΔVbd\frac{\Delta V_{b}}{d}= 0.6106\frac{0.6}{10^{- 6}} = 6 × 105 V/m
