Optical quantum chip doping materials
Ultra trace elements is added into the intrinsic semiconductor as impurities, the conductivity of the semiconductor can be significantly changed. The impurities incorporated are mainly trivalent or pentavalent elements. An intrinsic semiconductor doped with impurities is called an impurity semiconductor. The preparation of impurity semiconductors materials is generally doped in the intrinsic semiconductor at a ratio on the order of one part per million.
