Electronic configuration of germanium is 2, 8, 18 and 4. To make it extrinsic semiconductor small quantity of antimony is added
View answer and explanation
Correct option: C
The material obtained will be -type germanium which has more electrons than holes at room temperature
Option C is correct because antimony (Sb) is a pentavalent impurity, adding it to germanium creates an N-type semiconductor with more electrons than holes.
