We report the successful fabrication of a V-groove Al 0.5 Ga 0.5 As/GaAs/Al 0.5 Ga 0.5 As quantum wire system and the temperature-dependent photoluminescence (PL) measurement. The PL spectra are dominated by four features at 681, 642, 635 and 621 nm attributed to the luminescences from quantum wire,

The photoluminescence (PL) of In 0.55 Al 0.45 As/Al 0.5 Ga 0.5 As self-assembled quantum dots has been measured at 15 and 80 K under hydrostatic pressure. The lateral size of the dots ranges from 7 to 62 nm. The emissions from the dots with 26, 52 and 62 nm size have a blue shift under pressure, ind
We use time-resolved photoluminescence spectroscopy to probe the relaxation of excited states in In 0.5 Al 0.04 Ga 0.46 As/Al 0.08 Ga 0.92 As self-assembled quantum dots. The relaxation rate of excitons confined to the quantum dots increases by nearly an order of magnitude as the energy of the state
