Question

In an unblased p-n junction, holes diffuse from the p - region to n- region because

Answer 1

•IN AN UNBIASED P-N JUNCTION DIODE, HOLES DIFFUSE FROM THE P-REGION TO N-REGION BECAUSE the HOLE concentration in P-REGION is more compared to N-REGION

•IN AN UNBIASED P-N JUNCTION DIODE, HOLES DIFFUSE FROM THE P-REGION TO N-REGION BECAUSE of the diffusion of charge carriers

•The diffusion of charge carriers across the JUNCTION takes place from higher concentration to lower concentration.

Answer 2

In unbiased p-n junction, here is the diffusion of charge carries take place.

• Here the concept of higher to lower concentration came in place.
• As we know that p junction have holes in excess and n-junction has electrons in excess.
• But as it is unbiased due to which there is movement of holes from p to n junction.
• Because p has greater holes than n junction therefore transfer from the p to n junction.
