I am studying the reflection from a potential step. I have one interesting question.

When Kinetic energy $E$ > $U$ (potential energy), is it possible that we would have a probability wave for electrons, in the region past the potential step, with same kinetic energy $K$ (no energy change like quantum tunneling)?

  • $\begingroup$ Yes of course. What makes you think that would not be the case? If it can happen with E<U why would it not happen with E>U? The former is harder to grasp than the latter, surely. $\endgroup$ – Floris May 3 '17 at 12:22

  • $\begingroup$ Anyway, then it will be a dull probability graph- straight line. Not like the exponential one in tunneling. $\endgroup$ – Mockingbird May 3 '17 at 13:38
