Quantum Mechanics, Potential Step

    I have noticed that while we study the case where, E>Vo, and we write the wave functions in both regions, we don't consider the case where x tends to infinity and thus the solution disappears.
    (We typically do that to reduce unkniwn constants)

    But when we consider the case where E<Vo, and write the wave functions in both regions, we do that as x tends to infinity.

    Note that the difference between thojse two was that the solution in the first region, the exponentialnwas raised to a "power" containing the imaginary nb i, unlike in the second case..

    In the second case you deal with a bond states which goes to zero when ##x## goes to infinity.
