A) Germanium
B) Arsenic
C) Selenium
D) Boron
Correct Answer: D
Solution :
The n-type semiconductors are obtained when Si or Ge are doped with elements of group 15, eg, arsenic (As), while p-type semiconductors are obtained when Si or Ge are doped with traces of elements of group 13, ie, indium (In), boron (B). Note: The conductivity of semiconductors increases with rise in temperature.You need to login to perform this action.
