Question:

A p-type semiconductor in which doping was done of the order of 5.65 x \( { 10}^{ 6} \) atoms, the net charge on the sample becomes what?

Options:

1.6 x 5.65 x \( { 10}^{ 25} \)

- 1.6 x \( { 10}^{ 19} \)

zero

1.6 x \( { 10}^{ 19} \)

Correct Answer:

zero

Explanation:

Whether it is a p-type semiconductor or an n-type semiconductor, the total charge is always zero i.e. it is electrically neutral.
