摘要
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.
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.
