doped
v. C1 Advanced US //ˈdoʊpt// UK //dˈəʊpt// doped
v. to add a small amount of a different material to a pure substance to change its electrical properties. This makes the material conduct electricity better or in a specific way.
v. to introduce impurities into a pure semiconductor to modify its electrical conductivity. This process creates either an excess of electrons (n-type) or a deficiency of them (p-type).
The engineers doped the silicon to improve its performance.
By doping the semiconductor with boron, the researchers created a p-type material that conducts electricity when a voltage is applied.
The successful operation of a diode relies on the precise doping of its layers, where the interface between n-type and p-type materials allows for the controlled flow of current.
