Question

Reflection from a Step with E < V0: A beam of electrons, each with energy E=0.1V0 , is incident on a potential step with V0 = 2 eV. This is of the order of magnitude of the work function for electrons at the surface of metals. Calculate and graph (at least 5 points) the relative probability |Ψ#|# of particles penetrating the step up to a distance x = 10-9 m, or roughly five atomic diameters. (Hint: assume A=1.)
