PhD Project Description
My PhD research has investigated the electronic properties of nanocrystalline materials and the potential for fabricating inorganic optoelectronic devices via solution processing.This work has led to the development of a novel light-emitting device that uses colloidal CdSe/ZnS quantum dots as the emissive layer.
Thin film charge-transport layers enable controlled injection of electrons and holes into the quantum dots where they recombine and emit pure, narrow-linewidth light (approx 50 nm FWHM).
Previously Completed Research Projects
& Surface Steps in STEM
Honours thesis, Monash, 2005
This project investigated the use of advanced scanning transmission electron microscopy (STEM) to reveal surface steps and embedded stacking fault defects in crystalline silicon.
Multislice calculations provided simulated diffraction patterns containing contrast resulting from different defect features and crystal orientations. The resulting patterns were analysed as a basis for specialised detector geometries that are sensitive to intensity related to the defect under observation.
