Abstract

Carrier transfer in low-density InAs/InP dot arrays with a multi-modal dot size distribution is studied by means of steady-state photoluminescence. The transition from saturation of the inter-dot carrier transfer to the unsaturated regime is surely observed by analyzing the shape of the luminescence signal for decreasing excitation densities. We unambiguously show that larger size dots provide a competing but saturable relaxation channel for smaller quantum dot ground states.
