| Abstract: | The electronic properties of InAs quantum dots (QDs) grown on InAlAs/InP(0 0 1) were studied by using capacitance-voltage (C-V) analysis and photoluminescence (PL) measurements. The level positions of electrons and holes could be studied separately by using n- and p-type InAlAs matrices, respectively. The holes are found to be more confined than electrons in these kinds of dots. |
