Abstract

Optical absorption and photoluminescence were first used to study the electronic structure of nanometer sized semiconductor colloids. However, these techniques only provide information about the collective properties of large numbers of QDs and, due to a distribution in particie size, the luminescence signals are inhomogeneously broadened. With Scanning Probe Techniques such as Scanning Tunneling Spectroscopy (STM) and Scanning Near-field Optical Microscopy (SNOM), electrical and optical measurements on individual particles can be performed, avoiding problems arising from polydispersity. In the work described in this thesis the optoelectronic properties of semiconductor quantum dots, and charge transfer between such structures and a conducting substrate were studied in a novel way. For this purpose, metal substrates were provided with a (sub) monolayer of quantum dots; the opto electrical properties of the systems were investigated with time-resolved photoelectron chemistry.
