In an unbiased p−np-n junction holes from the p-region to nn-region because of:

Options

  1. AThe attraction of the free electrons of n-region.
  2. BThe higher hole concentration in p-region than that in nn-region.
  3. CThe higher concentration of electrons in the nn-region than that in the p-region.
  4. DThe potential difference across the p−np-n junction.

Correct answer

B. The higher hole concentration in p-region than that in nn-region.

Step-by-step solution

The higher hole concentration in P-region that in nn-region.
