Facility: Electron Microscope Unit
Category: Academic Staff

Education

PhD Physics, University of Bristol, UK (2015)

MSci PhysicsUniversity of Bristol, UK (2011)

Role

To train, aid and manage users on the JEOL F200 microscope

Research Interests

My interests lie in the application of electron microscopy methods to determine composition, structure and defect nature of semiconductors, mainly III-nitrides. My present research includes the application of electron microscopy to InxGa1-xN nanorods and films for use in LED and transistor devices.

My interests lie in the application of electron microscopy methods to determine composition, structure and defect nature of semiconductors, mainly III-nitrides. My present research includes the application of electron microscopy to InxGa1-xN nanorods and films for use in LED and transistor devices. Recent research has included:

-          the compositional profiling, using energy dispersive X-ray spectroscopy, of InxGa1-xN nanorods to understand the growth mechanisms of these structures,

-          the application of electron diffraction techniques to determine the structure of materials, mainly semiconductors and

-          the use of novel substrates, such as polycrystalline diamond, for improved thermal characteristics of semiconductor devices.
