Abstract

We calculate the bound-to-continuum transition amplitude in a biased GaAs/AlGaAs multiple quantum well structure. The continuum wave functions above the barrier bound on one side and free on the other extreme were normalized using the Dirac (delta) -function. The normalization renders that the amplitude of sinusoidal functions corresponding to different energies should be same in the far flat region. Calculated transition peak agrees well with the experimental results reported. Possibility of using complex energy representation to find the excited states is also discussed.
