Ultrafast optical response of InAs quantum dots for photoconductive applications

Not Accessible

Your library or personal account may give you access

Abstract

Optical pump-probe measurements have been performed on superlattices of self-organised InAs quantum dots embedded in GaAs. These structures exhibit subpicosecond photocarrier lifetimes when excited at 800 nm, which increase with the ex situ annealing temperature.
