Question

A group-14 element is to be converted into n-type semiconductor by doping it with a suitalbe impurity. To which group this impurity belong?

Answer 1

Answer:

Explanation:

n-type semiconductor means conduction due to the presence of excess of negatively charged electrons. Hence, to convert group 14 element into n-type semiconductor, it should be doped with group 15 element.

Answer 2

Answer:

An n-type semiconductor conducts because of the presence of extra electrons.

Therefore, a group 14 element can be converted to n-type semiconductor by doping it with a group 15 element.
