摘要：
The authors have used magnetophotoluminescence for the determination of the lateral anisotropy of buried quantum dots. While the calculated shifts of the energies of higher radiative transitions in magnetic field are found to be sensitive to the lateral elongation, the shift of the lowest transition is determined mainly by the exciton effective mass. This behavior can be used for a fairly reliable determination both the effective mass and the elongation from spectra containing at least two resolved bands. (c) 2006 American Institute of Physics.
