摘要：

We report optical spectroscopic results of a single self-assembled In0.75Al0.25As/Al0.3Ga0.7As quantum dot. The polarization-dependent shift of the Zeeman splitting in a single InAlAs quantum dot (QD) has been observed. The induced Overhauser field is estimated to be similar to0.16 T in this InAlAs QD and the magnitude is shown to be controllable by the degree of circular polarization of excitation light.
