Paper Abstract

Photocurrent and capacitance spectroscopy are used to investigate a Schottky barrier structure containing a single layer of self-organized InAs/GaAs quantum dots. We show that the temperature dependence of the photocurrent signal from the quantum dots is governed by thermal escape of electrons as the faster carriers.
