We performed spatially-resolved photoluminescence (PL) and photoluminescence excitation (PLE) spectroscopy of T-shaped quantum wires (QWRs). To realize novel one-dimensional (ID) properties of GaAs QWRs, we found it important to reduce their size into 5-nm scale. [1,2]. Controllable fabrication of such QWRs with high quality was achieved with the cleaved edge overgrowth method. [3]
