1. The problem statement, all variables and given/known data Consider a square hill barrier produced by a 10V potential. Incident upon this barrier is a steady stream of 5eV electrons. (a) If half the electrons are transmitted, how thick is the barrier? (Please derive the transmission probability rather than merely quoting it.) 2. Relevant equations TISE ΨE = H*Ψ sorry I don't know how to put the ^ over the H for the hamiltonian operator. 3. The attempt at a solution Normally when trying well and barrier questions I would start by drawing out the well or barrier in question. However in this question the issue I'm having is that I don't even know how to draw it. I know it's a barrier and I think it has total E=10V but really am unsure what I'm supposed to do with the stream of 5eV electrons. I've never had a question like this with electron volts before, all my previous questions will just say something like "Total energy E=9V0 V=0 for x<0 & V=5V0 for x>0 " which I know how to draw and visualize. Any help is appreciated, thanks.
