Updated On: Jul 6, 2022
- The material obtained will be n-type Germanium in which electrons and holes are equal in number
- The material obtained will be p-type Germanium
- The material obtained will be n-type Germanium which has more electrons than holes at room temperature
- The material obtained will be n-type Germanium which has less electrons than holes at room temperature.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Antimony is a fifth group impurity and is therefore a donor of electrons. When it is added to germanium, the material obtained will be $N$?
