摘要：
Heterostructures with In(Ga)As/GaAs quantum dots and quantum wells grown at low substrate temperature were studied by reflection high-energy electron diffraction, transmission electron microscopy, and photoluminescence methods. It is shown that InAs deposited onto (100) GaAs surface at low substrate temperature forms 2D clusters composed of separate quantum dots. Optical spectra of structures containing such clusters demonstrate emission in the 1.5-1.6 mum range. (C) 2003 MAIK "Nauka / Interperiodica".
