My PhD work involved the development of a new characterization technique for semiconductor strained layer structures. This was based on ‘the wedge technique’ whereby specimens were obtained by cleaving and looked at in the TEM through the tilted 900 corner. The precisely know geometry then enabled strain value calculations in the structure, modelling of TEM images and comparison with experimental images. I was the first to apply finite element methods to strained layer semiconductor systems for purposes of quantitative determination of strain distributions.
I have investigated self-organized growth phenomena in strained III-V semiconductor hetero systems and SiGe and established a universal roughening transition curve (temperature versus strain). This work led on to investigations of strain driven compositional segregation in semiconductor quantum wells, wires and dots.I developed a code for 3-D composition analysis from EDX measurements.
I have carried out investigations of bandgap states at extended defects in wide band gap semiconductors and the development of valence band electron energy loss spectroscopy (VEELS; this involved work carried out on a dedicated STEM, the NorthWest STEM at Liverpool) as well as in structural studies and investigations of surface plasmon phenomena in nanocarbons (GR/R81671), semiconductor and metal nanospheres
I was co-investigator on the above grant award 'Novel electron energy loss spectroscopy of carbon, carbon-nitride and boron-carbon-nitride nanostructures', EPSRC, 2002-2005, ~£202,000
Recently I have become involved in 2-D research, I am very interested and made the initial suggestion to explore the potential of 2-D Di-chalcogenides and MXene as topological insulators.
I have taught one year of quantum mechanics and two years of Electromagnetism since being at Limerick University.
I was given the opportunity to teach the particle physics course in the Physics Department at UMIST for two years and have taught on TEM short courses in the Material Science Centre at Manchester. I give weekly tuition including both, theoretical and the practical to students on using the TEM.
