Photoluminescence of dome and hut shaped Ge(Si) self-assembled islands embedded in a tensile-strained Si layer
- Institute for Physics of Microstructures RAS, GSP-105, 603950 Nizhny Novgorod (Russian Federation)
The effect of the growth temperature (T{sub g}) on photoluminescence of Ge(Si) self-assembled islands embedded between tensile-strained Si layers was studied. The observed redshift of the photoluminescence peak of the dome islands with a decrease of T{sub g} from 700 to 630 deg. C is associated with an increase of Ge content in the islands and with the suppression of smearing of the strained Si layers. The blueshift of the photoluminescence peak with a decrease of T{sub g} from 630 to 600 deg. C is associated with a change of the type of islands on surface, which is accompanied by a decrease in islands' height.
