Co-doping and transition metal doping of Gallium Nitride. Spintronics is poised to create a new paradigm in device electronics. Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet.

Gallium nitride (GaN) containing trace amounts of transition metals (such as Fe,Ni) is a promising dilute magnetic semiconductor for spintronics as this material exhibits magnetic behaviour above room temperature. However, the electronic and magnetic properties of these GaN-based semiconductors have not been optimized, as yet. This project aims to establish and test a new growth strategy, know as the co-doping method, for the fabricate of high quality transition metal doped GaN. A broad range of complementary spectroscopic techniques will be used to refine this new fabrication technique.Read moreRead less
Environmentally benign polymer solar cells. The project aims to prepare polymer solar cells, by developing water-compatible conjugated materials for the active layer.

Transformational lighting: changing the way we live. This Fellowship aims to advance the science of ultrathin efficient lighting technologies based on low embedded energy organic light-emitting diodes (OLED). By creating innovative semiconductor materials and diode architectures that optimise each step in light generation—from charge injection, transport and capture to light emission—the project aims to deliver transformative OLED lighting that is more efficient than standard fluorescents by 50%. The intended outcomes of the project are design rules for OLED componentry, including thin, flexible architectures for deployment in a range of environments. The project would prototype the new technology at scale, demonstrating a large-area lighting module with power efficiency of 150 lm/W.Read moreRead less
Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon anneali ....Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon annealing. This effect has been linked with higher charge mobilities, and a tighter molecular packing is locked in upon cooling. The potential applications of these high performance organic semiconductors includes chemical/biosensors, electronic paper, and radio frequency identification cards.Read moreRead less
