| Abstract(in English) | Fordevice appliCation of quantum dots, it is important to clarify the electronic states in quantum dits (QDS). We have determined the binding energy of electron S-bound state in self-assembled InAs QDs embedded in GaAs matrix by using the structure of modulation-doped QD infrared photodetectors (MD-QDIPs). From dark current measurements and mid-infrared photocurrent measurements, it was found that the binding energy of electron 1s-bound states in relatively Small QDs (diameter～15nm) and relatively large dots (diameter～45nm) are～120meV and ～390meV respectively. Similarly by mid-infrared photocurrent measurements, the binding energy of hole s-bound states in relatively sma11 dots (diameter～20nm) was determined to be ～110meV. |
