In an unbiased p-n junction, holes diffuse from the p-region to n-region because of
Options
(a) the potential difference across the p-n junction
(b) the attraction of free electrons of n-region
(c) the higher hole concentration in p-region than that in n-region
(d) the higher concentration of electrons in the n-region than that in the p-region
Correct Answer:
the higher hole concentration in p-region than that in n-region
