Question

Which is used as n-type dopant for silicon in semiconductor industry?​

Answer 1

Explanation:

In contrast, a semiconductor in a pure undoped form is an intrinsic semiconductor. In silicon doping, there are two types of impurities: n-type and p-type. In n-type doping, arsenic or phosphorus is added in small quantities to the silicon.

Answer 2

Answer:

To make the n-type semiconductor, pentavalent impurities like phosphorus or arsenic are added. Four of the impurities' electrons form bonds with the surrounding silicon atoms. This leaves one electron free. The resulting material has a large number of free electrons.
