Current PhD Positions

Over the past two decades, developments in nanostructured materials have enabled huge progress in electronics and optoelectronic devices. However, novel materials, particularly those with nanoscale dimensions present unique challenges for characterisation, where surface-effects become dominant and light-matter interactions can be modified by wavelength-scale geometry.

In my group, we are primarily concerned with how energy moves in nanostructured materials for optoelectronics applications (LEDs, lasers and photovoltaics). To study this, my group is developing automated spectro-microscopy techniques coupled to femtosecond lasers to allow the controlled study of carrier dynamics at the sub-micron length scale and sub-picosecond timescale. By combining advanced photonic characterisation with machine vision, we seek to take advantage of added information revealed through big-data approaches. Typical PhD level projects include:

  1. Development of novel spectroscopic methods: Novel materials often require novel spectroscopic approaches. Our group develop useful tools to address specific challenges - this recently includes single-photon interference spectroscopy, micro-transient absorption tools, and non-linear mapping for 3D reconstruction
  2. Semiconductor nanowire spectroscopy: While nanowires have high promise as future optoelectronics components, wire-to-wire inhomogeneity presents a unique challenge. We develop statistical approaches to understand and optimize this novel material
  3. Three-dimensional optoelectronic device characterisation: Nanoscale structured materials tend to exhibit highly inhomogeneous properties. The relationship between these local properties and macroscopic behaviour is unclear – by mapping properties in 3D, we relate these measurements to bottom-line efficiencies.
