8. The theory in [7] was for bulk semiconductors, while quantum wells are usedfor the measurements reported here. A. Najmaie, R. D. R. Bhat, and J. E. Sipe (private communication) have repeated the calculations in [7] for quantum wells. While there are quantitative differences, the qualitative behavior of the transverse currents in the x-y plane is the same. However, the motion in the longitudinal z direction reported in [7] is restricted in the MQW.

15. We also measured the charge current for crossed linear polarization using charge collection with conventional electrodes (not shown), as was done in Ref. [4], and observed no charge current in the x direction. There was a small charge current in the y direction, but as predicted by Ref. [7], it was much weaker than the charge current for the same linear or the same circular excitation reported in Ref. [4].
