Question

please solve this problem ​

Answer 1

● 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...
