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.
Description
This 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.
