Semiconductor resistance

  1. Nov 12, 2011 #1
    Hello All;
    This is a question I found in semiconductors and devices by Kanaan Kano.

    Basically, the volume of a bar of Silicon is given at 300 K [1x0.01x0.2 cm]. How would you find the resistance of the bar if it is intrinsic.

    Also, what will be the new resistance after doping of 10^15 donors. What about doping of 10^15 Acceptors ?

    The resistance of the bar depends on the conductivity. And the conductivity depends on the doping concentration. So first find the conductivity. You need mobility of both electrons and holes for this. See if you can find this in text's appendix
