Professional duties

  • in charge of TEM care and operation in the Electron Optics Suite at the Manchester Materials Science Centre (the instruments comprise a CM30, a CM200, a Tecnai F30 and a probe corrected Titan ChemieSTEM)
  • in charge of various TEM specimen preparation equipment, assisting in specimen prep
  • instructing and assisting researchers and students in the use of the TEMs; the Electron Optics Suite is a University facility, as well as open to industry; hence my duties encompass liaising with Departments and Schools across the whole University as well with industrial companies and frequent and regular dealings with FEI
  • partaking in research activities with various groups (nano-carbon research,..........)
  • lecturing on University Degree courses (particle physics), on short courses as well as giving small-group and one-to-one tuition
  • have been in charge of a current booking system for the TEM’s and SEM’s which I have programmed and maintain on a commercial web host site.
  • use of software packages for image and spectroscopic data evaluation and simulation (e.g., TEMSIM, Q-STEM, DM)

 

Research

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.

 

Teaching

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.

 

Academic Enterprise and Knowledge Transfer

  • Industrial collaboration with FEI and Gatan. In my role as care taker of the electron optics activities in the School of Materials I mediate daily requests by industries for provision of electron microscopy services and I engage in company specific research issues.
  • Collaborations within academia include
  • other research groups within the School of Materials itself as well as with the University of Manchester •Photon Science Institute •School of Electronic Engineering •School of Physics •School of Chemistry •MACE •School of Earth Sciences
  • the School of Engineering at Liverpool University (especially instrumentation development for EELS, GR/N64908/01)
  • the Centre for Superhard and Novel Carbon Materials in Moscow
  • the Electronic Engineering Department at the Chinese University of Hong Kong
  • the NortWest STEM at Liverpool University
  • the Daresbury SuperSTEM
  • the ER-C and IFF at the FZ Juelich
