PhD student and post-doc positions at TU-Delft, The Netherlands.
Topic: Synthesis and characterisation of inorganic semiconductor quantum dots and nanowires for
Q-dot based solar cells
In the Chemical Engineering Department of the Delft University of Technology PhD student and
post-doc positions are available for synthesis and/or opto-electronic characterisation of
semiconductor quantum dots for solar cells.
Project and job description
In close collaboration with the Kavli Institute of Nanoscience in Delft, the nanochemical engineers
at TU Delft aim to push new scientific discoveries towards utilisation. Collaboration between the
Kavli Institute and the Department of Chemical Engineering has resulted in several new research
objectives, focused on quantum dot arrays, core-shell quantum dots, nanowires and nanoporous
materials. Composite quantum dots and nanowires are junctions between different materials on a
nanometer scale. In core-shell quantum dots, nanowires, and nanoporous materials various
components act together to create new functionalities. Engineering such functionalities towards
better performance is essential and demands minute control over the chemistry during synthesis.
Research of the PhD student and post doc is focussed on the design, synthesis and
characterisation of functional (core-shell) quantum dots and nanowires aiming at advanced solar
cells based on nanomaterials.
Synthesis and Characterisation
Synthesis of (core-shell) Q-dots and nanowires is part of the research activity. Wet chemical routes
are applied, based on well-documented synthesis techniques. Semiconductor Q-dots of interest
include: CdSe, PbSe, PbS, and CuInSe2. Synthesis of these materials is optimised towards low
defect concentrations, narrow size distribution, and the application of well-chosen organic and
inorganic capping materials. In the opto-electronic Materials group a wide variety of state-of-the-
art research facilities are available. Optical characterisation includes femtosecond and nanosecond
photoluminescence and transient absorption spectroscopy. Furthermore, pump-probe techniques
with GHz and THz microwave probes are also available. With these techniques carrier dynamics of
the excited state, such as impact ionisation, Auger cooling, and electron transfer processes in
donor-acceptor systems can be investigated in depth.
Requirements
Chemists and physicists with interest in the synthesis and / or characterisation of semi-conductor
quantum dots are invited to respond.
