Doping of $As$ with $Si$ is called :
AnswerClick to flip back
A
n-type semi-condutor
💡 Explanation:
$As$ is a member of group $V$ and has 5 electrons in its outermost shell.
When $Si$ is doped with group $V$ elements such as $As$ then, $Si$ forms four bonds with $As$ and one extra electron is left free for conduction.
Since the conduction is due to the presence of free electrons, therefore, it is known as n-type semiconductor.
Therefore, the option is A.
