Abstract
High brightness light emissions from single InAs/GaAs quantum dots (QDs) epitaxially grown directly on silicon substrates are realized for the first time. The grown structures contain a low quantum dot density of about 10(8) cm(-2). Low-temperature spatially resolved photoluminescence (PL) measurements illustrate bright single QD emissions with relatively sharp excitonic lines comparable to PL spectra of near-surface QDs grown on GaAs substrates.
