摘要：
Sulfide passivation has been used to reduce the surface nonradiative recombination rate in micro- disk mesas based on (AlGaIn)As/GaAS heterostructures the active region of which is constituted either by ten GaAs/AlAs quantum wells or by a sheet of InAs/In0.15Ga0.85As quantum dots. It is shown that passivation leads to a substantial rise in the photoluminescence intensity for mesa structures of all types.
