The device dissipates power which generates heat, thus heating the silicon crystal to a temperature of T = °K. Use: m*n = 1.08 m0, m*p = 0.56 m0, Egap = 1.12 eV = Ec with Ev = 0 as the reference, and m0 is the free electron mass = 9.11 x 10-31 kg. Assume Boltzmann statistics applies and do the following:   (a) Find the intrinsic Fermi level EFi                                                             2 pts (b) Find the intrinsic carrier concentration ni = pi                                      2 pts (c) Find EF – Ev                                                                                               2 pts (d) Find Ec – EF                                                                                               2 pts (e) Calculate the respective minority carrier concentrations n0 or p0      2 pts

A student uses the microscope to view bacteria, starts with lower magnification objective to higher ones. Accidentally the slide breaks while the student was using the 40X objective.  1: What is the other name of this objective ? 2: Why do you need to use oil with the highest magnification?
