With which one of the following elements silicon should be doped so as to give p - type of semiconductor?

  • Germanium

  • Arsenic

  • Selenium 

  • Boron 

Solution

D.

Boron 

The n- type semiconductors are obtained when Si or Ge are doped with elements of group 15, eg, Arenic (As), while p-type semiconductors are obtained when Si or GGe are doped with traces of elements of group 13, ie indium (In), Boron (B).
