= Dopant
{wiki=Dopant}
A dopant is a material that is added in small quantities to a semiconductor to modify its electrical properties. This process is known as doping. The primary purpose of doping is to control the concentration of charge carriers in the semiconductor material, which can enhance its conductivity. In semiconductors, the two main types of dopants are: 1. **N-type dopants**: These have extra electrons, which can increase the number of free electrons in the semiconductor.
