Influences of Si sheet doping densities on the morphological, conductive and optical characteristics of InAs/GaAs quantum dots

Ke-Fan Wang, X. G. Yang, Y. X. Gu +3

The influences of Si sheet doping levels on the properties of InAs/GaAs quantum dots (QDs) are investigated by atomic force microscopy (AFM) and photoluminescence (PL). AFM measure…
