प्रश्न
Which of the following is true about the charge acquired by p-type semiconductors?
विकल्प
Positive
Neutral
Negative
Depends on concentration of p impurity
उत्तर
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.
