Science jobs from Tyndall National Institute: job description
A funded PhD position is currently available on the chemical synthesis and
characterisation of Group IV (Si, Ge) nanocrystals, and their subsequent
incorporation into hybrid organic/inorganic optoelectronic devices, within the
Nanotechnology Group at the Tyndall National Institute, starting in October
2011. The use of semiconductor nanocrystals (NCs) that exhibit quantization
effects in solar photo-conversion devices (mainly quantum dots, quantum wires,
and quantum rods) is presently attracting a great level of interest. Such
NC-based devices used as photovoltaic cells are now labelled third generation or
next-generation photovoltaic devices, as new advances in the photophysics allows
for the possibility of these inexpensive materials to be incorporated into
device structures with potential efficiency much higher than the thermodynamic
limit for single junction bulk solar cells.
DescriptionThis research project will focus on: • Synthesis of a range of
size-monodisperse Group IV nanocrystals with controlled doping for tuning of
photophysical and optoelectronic properties. • Detailed nanoscale
characterisation of the structural, photophysical and optoelectronic properties
of the as-synthesised nanocrystals. • Investigation of methods for self- or
directed-assembly of silicon nanocrystals at technologically relevant
interfaces. • Fabrication and interfacing to hybrid nanoscale organic/inorganic
devices for photovoltaic applications. • Detailed device characterisation under
inert and ambient atmospheric conditions. The successful student will receive
training in all research methods required, and will work alongside experienced
professional researchers within the nanotechnology group, attend conferences and
publish in high impact journals. Applications are invited from scientists and
engineers who hold (or expect to obtain before October 2011) a first or second
class honours undergraduate degree in chemistry, physics, materials science or a
closely related discipline.
