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 ?
