doping
The addition of dopants to a semiconductor to produce components of semiconductor devices such as transistors and solar cells. Through doping, a semiconductor material may acquire a surplus of positive charge carriers and become a p-type semiconductor or a surplus of negative charge carriers and become an n-type semiconductor. If two differently contaminated semiconductor layers are combined, then a so-called p-n junction results on the boundary of the layers.
