Abstract

Low-dimensional semiconductor structures grown by molecular beam epitaxy on a patterned (311)A GaAs substrate are investigated by near-field spectroscopy at a temperature of 10 K. In particular, the two-dimensional potential profiles of quantum wire and coupled wire–dot structures are determined from photoluminescence (PL) measurements with a spatial resolution of 150 nm. Also presented is an optical method for investigating carrier transport in low-dimensional systems involving performing spatially resolved PL excitation measurements on the wire–dot structure.
