This work numerically solves the effective mass Schrodinger equation and shows that the capture times are strongly influenced by details of the continuum states not accounted for by the approximate wave functions. Results show that calculations of capture time for phonon mediated carrier capture from a wetting layer into a quantum dot depend critically on the approximations used for the wetting layer wave functions.
