Optical Study of Carrier Transfer in Strain-induced Quantum Dots
Published online by Cambridge University Press: 10 February 2011
Abstract
We have studied excitation transfer from the host quantum well to strain-confined quantum dots. We find that there is a long-lived intermediate state acting as a reservoir, holding the excitation before it is thermally activated over a barrier to reach the quantum dot. The barrier height increases monotonically with dot size.
