Optical measurements of carrier relaxation and transport in single GaAs v-groove quantum wire structures

Abstract:

Single GaAs v-groove quantum wire structures, of varying width, have been studied using near-field and far-field photoluminescence (PL) and photoluminescence excitation (PLE) techniques. Strong non-thermal behaviour has been observed in complex quasi-1D/2D systems at temperatures below 40 K. Spatially resolved PL measurements in the presence of an applied voltage provide information about the distribution of current in the grooves. We find evidence of real-space transfer of carriers at higher...
