Question

Which of the following is true about the charge acquired by p-type semiconductors?

Options

  • Positive

  • Neutral

  • Negative

  • Depends on concentration of p impurity

MCQ

Solution

Neutral

Explanation:

p-type semiconductors by itself has mainly positively charged carriers (holes) which are able to move freely. It is however, still netural because the fixed acceptor atoms having accepted electrons are negative.
