Question

In unbiased p-n junction, holes diffuse from the p-region to n-region because free electrons in the n-region attract them. State true/false.

Answer 1

Dear Student,

# Given statement -

In unbiased p-n junction, holes diffuse from the p-region to n-region because free electrons in the n-region attract them.

◆ Answer -

False. (because diffusion takes place across concentration barrier not due to electrostatic force.)

● Corrected statement -

In unbiased p-n junction, holes diffuse from the p-region to n-region because hole concentration in p-region is more as compared to n-region.

Hope this helps you...
