PhD student (4 years) or post-doc (2-3 years) position available in the Section Optoelectronic
Materials at Delft University of Technology in The Netherlands.
Topic: ultra fast laser spectroscopy on new materials for solar cells and LEDs
Job description
The project involves studies of the nature and ultrafast dynamics of excited states (excitons) and
charge carriers in materials for application in the next generation solar cells or light-emitting
diodes. Materials of interest include conjugated polymers, inorganic nanoparticles and
nanostructured composites. Excitons and charge carriers will be produced by pulsed irradiation of
the material with laser or high-energy electron pulses with a duration in the femto- to picosecond
time-domain. The dynamics of these transient species will be probed by femtosecond optical
pulses and terahertz conductivity measurements. Processes to be studied include (non)radiative
decay of excitons in competition with exciton dissociation into free charge carriers, exciton-
exciton annihilation, charge carrier mobility and kinetics of charge recombination.
The knowledge to be obtained will contribute to the development of the next generation opto-
electronic devices including solar cells and LEDs.
Requirements
The candidate should have a doctorate and a relevant background in chemistry or physics. Specific
experimental experience with pulsed femtosecond laser systems is desirable, however, not
required.
