Name the two types of atoms used for doping of Ge/Si.

Short/Brief Note
Advertisements

Solution

Doping increases the conductivity of a semiconductor.

For doping pure Si, Ge, and pentavalent phosphorus is used to convert it to the n-type semiconductor.

Trivalent aluminium is used to convert pure Si, and Ge to the p-type semiconductor.
