1. Show by elementary integration that the net steady-state volume generation-recombination rate of electrons (or holes) in a volume element dxdydz is given by the net electron current flowing out of the volume element.

2. Given V_n(x)=V_n(0) + [V_N(L)-V_N(0)](x/L)² which is measured in an n-type Si sample, what are the electron and hole generation-recombination rates as a function of x to give this current in the 1-d n-Si bar in problem?
