Abstract
The decay time of luminescence from a multi-quantum well has been measured at 20 K by using a cw mode-locked Kr laser and a synchroscan-streak camera. The decay time was found to increase with applied electric field. The increase is considered to be attributable to a field-induced carrier separation. The decay time depends on the observed wavelength of luminescence. This dependence changes with the electric field, suggesting that the energy-decreasing rate of excitons becomes slower in the presence of an electric field.Keywords
