1. The problem statement, all variables and given/known data I am a beginning quantum mechanics student, and I need to solve a journal paper that uses the step potential fairly simply. I've been searching for (literally) days, but everything seems to be far too complicated. Can someone please point me in a direction, or offer some suggestions? 2. Relevant equations 3. The attempt at a solution I've searched iop, physics letters, aip and solid state electronics. I've used parameters like "heterojuctions" "step potential limiting case" "scattering matricies" I really appreciate any help - this is extremely frustrating, time consuming and unproductive. Thanks!!
