Paper Abstract

We present results concerning the influence of organometrallic vapro phase epitaxy (OMVPE) grwoth paramters under ultra low V/III ratio on the surface morphology and temperature-dependent photoluminescence. Due to Indium segregation inteh 2D InAs wetting layers and accumulation from multi-atomic step edge on (001) 2° off toward (111) n-type GaAs substrate, self-assembled InAs quatnum dot formation takes pace aroudn or above 2D InAs islands while ~ one monolayer of InAs is regularly grown on GaAs substrate. It is attributed that the desorbed Indium Recaptured and nucleated effect on edge along (110)-orientation of GaAs substrate.
