15. We have neglected the contribution to the absorption by the heavy holes located in the narrow well, since their mass is much heavier than that of the electrons.

18. There has recently been alot of discussion on the superluminal behavior of the shifting of the THz wave forms in highly absorbing medium (see Ref. 17). While it appears at first glance that the peak velocity passes through the sample with speeds greater than that of light, the shifting is actually a consequence of a phase shift of the THz wave as it enters a highly conducting medium. This phase shift is small and therefore generally not observable, but it does dramatically effect the behavior of the THz pulses when they are measured in the time domain.
