摘要
We investigated the optical properties of two monolayers of CdSe sandwiched by ZnSe layers grown by molecular-beam epitaxy on GaAs substrates with a vicinal tilt of 2degrees in the [111] direction. By varying the spatial resolution from 10 mum down to 500 nm, sharp photoluminescence lines due to the recombination of excitons confined into quantum dots could be observed at low temperature. The dot density could be as low as approximate to10(9) dots/cm(2), which is smaller than previously reported values by at least one order of magnitude. (C) 2003 American Institute of Physics.
