| Abstract: | We used the micro-Raman spectroscopy to investigate the V-grooved quantum well wires (QWWs), and first observed and assigned the Raman spectra of single QWW. They were the disorder induced modes at 223 and 243 cm−1, confined LO mode of GaAs QWW at 267 cm−1, and higher order peaks of disorder induced modes at 488 and 707 cm−1. |
