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

Options

  1. AGermanium
  2. BArsenic
  3. CSelenium
  4. DBoron

Correct answer

D. Boron

Step-by-step 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.
