PhD student position available in Delft The Netherlands
Project title: Optoelectronic Properties of Quantum Dot Solids
A position is available for a PhD student to study new functional metamaterials based on semiconductor quantum dots. The combination of quantum dots with different size or composition leads to optoelectronic properties that are of great promise for application in e.g. solar cells, transistors, catalysis, labeling and bio-medical testing. The project is part of a collaborative research program with the University of Utrecht and the Kavli Institute for Nanoscience in Delft.
The project focuses on fundamental studies of electronic excited states (excitons) and charge carriers in thin films consisting of a combination of self-organizing quantum dots, such as CdSe, CdTe, PbSe, PbS, InAs. You will study the dynamics of excitons and charge carriers with femtosecond and nanosecond pump-probe laser techniques, including microwave and terahertz conductivity measurements. In addition high-energy electron pulses can be used to specifically generate charges. The aim is to provide fundamental insights into the effects of material composition on exciton and charge dynamics. You will study to which extent charge generation by photon absorption can be optimized.
Particular attention will be paid to charge generation in donor-acceptor systems. The mechanism of motion of excitons and charges from one quantum dot to another will be characterized.
