5cm T=300K and VT = kT/q = 0.026V. %3D 1cm 1. You are given a 1mm x 1cm x 5cm silicon wafer, shown above. The room is at 300K, and you may assume total ionization. (a) How many carrier electrons are there in total? You decide to dope the Silicon wafer to make it an n-type wafer, but you have to make sure that it doesn't become degenerate. (a) Which element will you use to dope? (b) What is the maximum doping concentration that you can use?
