Decay length of Half Square Well

  1. Dec 9, 2007 #1
    If one wall is at infinite potential, and the other at some finite potential, what is the decay length outside of the well?

    I was thinking it might be twice that for a finite square well.

    Also can anyone provide some information regarding these wells? Google is (surprisingly) devoid of any information on these.

    Thanks a lot.

    Schrodinger's equation is separable and not too difficult to solve for the half-infinite square well. Why not just work out the math and answer your questions yourself?
