In an unbiased p – n junction, holes diffuse from the p – region to n – region because
A
Free electrons in the n region attract them
B
They move across the junction by the potential difference
C
Hole concentration in p – region is more as compared to n – region
D
All of these
Answer
Hole concentration in p – region is more as compared to n – region
Explanation
Solution
: In an unbiased p-n junction, the diffusion of charge carries across the junction takes place from higher concentration to lower concentration, thus option (3) is correct
