Question

How will you dope a pure silicon crystal to obtain a p-type and an n-type semiconductor?

Answer 1

these are the doping method

Answer 2

Hey dear,

● Doping semiconductors -
- Doping is the process of adding impurities to intrinsic semiconductors to alter their properties.
- Normally Silicon or Germanium are doped with impurities which increases conc of carriers.

● n-type semiconductor -
- Typical pentavalent (column V) impurity
- Usually Arsenic/Phosphorous
- Majority carrier - electrons

● p-type semiconductor -
- Typical trivalent (column III) impurity
- Usually Boron/Aluminium
- Majority carrier - holes

Hope this help you...
