A step pn junction diode is made in silicon with the n side having N'D = 2x10^16 cm^-3 and the p side having a net doping of N'A = 5x10^15 cm^-3. 1). Draw to scale the energy band diagram of the junction at equilibrium. 2). Find the built-in voltage, and compare with the value measured off your drawing in 1). There are 9 parts to this question, but I cannot seem to find out how to start it off. I've tried for 3 hours and couldn't make any progress. The other parts are somewhat related.
