On doping Ge metal with a little of In or Ga, one gets
A
‐ type semiconductor
B
‐ type semiconductor
C
insulator rectifier.
Text Solution
Verified by ExpertsThe correct answer is:
A
‐ type of semiconductors are produced due to metal deficiency defects by adding impurity containing less electrons ( i . e . atoms of group 13). Ge belongs to Group 14 and In to Group 13. Hence on doping 
‐ type semiconductor is obtained. This doping of Ge with In increase the electrical conductivity of the Ge crystal.
