Consider a traveling (electrons) wave moving in the +x direction
approaching a step barrier of height 1 eV; that is V = 0 for x <
0, V = 1.0 eV for x ≥ 0. For x < 0, there will be both the
traveling wave in the +x direction. For x ≥ 0, only a solution
corresponding to motion in the +x direction exists. By solving the
Schrödinger wave equation in both x < 0 and x ≥ 0...
