6.2 Growth and structure of semiconductor quantum wells
... functions with differing quantum numbers are not necessarily orthogonal to each other because of the differing decay constant in the barrier regions. This means that there are small departures from the selection rule of a infinite quantum well. However these non-zero transitions are usually weak, an ...

homework 2, due October 3rd
... Consider a particle described at some particular instant of time by the wave function ψ(x) = Ae−ax . 1. Determine A so ψ is normalized. 2. Compute hxi, hx2 i and σx2 = h(x − hxi)2 i. 3. Compute hpi, hp2 i and σp2 = h(p − hpi)2 i. 4. Show that by changing a one can make either σx2 or σp2 small, but n ...
