摘要
The change of phonon energies of annealed InGaAs/GaAs quantum dots (QDs), was observed using selectively excited photoluminescence. X-ray diffraction and optical anisotropy analysis shows that the QDs' structure mainly changes along the growth direction. (C) 2002 Elsevier Science B.V. All rights reserved.
