Question
What is doping ?
Open in App
Solution
The conductivity of metal is increased by adding an appropriate amount of suitable impurity. This process is known as doping.
It can be performed with an impurity that is electron-rich or electron-deficient than the intrinsic semiconductor silicon or germanium.
