Self-assembling CdSe, ZnCdSe and CdTe quantum dots on ZnSe(100) epilayers

CdSe quantum dots were fabricated on ZnSe(100) epilayers by the molecular b eam epitaxy (MBE) and the solid phase reaction method. ZnCdSe quantum dots were prepared by MBE and the atomic layer epitaxial method. CdTe quantum do ts were fabricated by alternate supply of Cd and Te beams. Nanoscale surfac e structures of these self-assembling dots were observed using an atomic fo rce microscope. Broad emissions were observed in the photoluminescence of t hese capped samples.
