Abstract

A nonthermal, quasimonoenergetic exciton distribution is observed in time-resolved photoluminescence measurements up to 150 ps after excitation if a quantum wire is excited resonantly and with low excitation density of 102 cm-1. The scattering rate increases only slowly with increasing exciton density. This is the first evidence in optical experiments for strongly reduced exciton-exciton scattering rates in one-dimensional systems.
