We have investigated temperature dependent photoluminescence of both buried and surface selfassembled InAs/GaAs quantum dots with an areal density up to $ 10 11 /cm 2 . Different from the buried quantum dots, the peak energy of surface quantum dots shows a blueshift relative to the bulk material var
