    Doping can be done with an impurity which is electron rich or electron deficient as compared to the intrinsic semiconductor silicon or germanium. Doping of silicon with boron leads to

    A)  n-type semiconductor

    B)  p-type semiconductor 

    C)  metal                

    D)  insulator

    Correct Answer: B

    Solution :

    Semiconductor doping is the process that changes an intrinsic semiconductor to an extrinsic semiconductor. The p-type semiconductor have a larger hole concentration than electron concentration, p-type semiconductors are created by doping an intrinsic semiconductor with acceptor impurities. The most common doping element for p-type semiconductor are silicon and boron.
