For example, nitrogen doping can enhance mechanical strength of diamond, and heavy doping with boron ( several atomic percent ) makes it a superconductor.

"If I'd got results in the World Championships next year, I might have got into heavy doping . . . to become an Olympic champion . " _ _ __

To combat drain-induced barrier lowering ( DIBL ), MOSFET channels are more doped near the source and drain terminals to reduce the size of the depletion region in the vicinity of these junctions ( called " halo doping " to describe the limitation of this heavy doping to the immediate vicinity of the junctions ).
