The growth and photoluminescence of Ge(Si) self-assembled islands on strained Si 1Γ€x Ge x layers (0 < x < 20%) has been investigated. Both island size and density increase when the Ge content in the predeposited Si 1Γ€x Ge x alloy increases. The increased island density is associated with an enhanced
