My research
is based on the study of novel materials or new materials combinations
for potential device applications. These materials include
metals, oxides, nitrides with properties which include superconductivity,
magnetism and ferroelectricity. This work makes use of the
Group's thin film deposition facility and often requires the
equipment within the University Nanoscience Centre for
device fabrication.

These figures show how we fabricate devices using our focused ion beam system to enable the measurement of the resistance of metallic heterostructures perpendicular to the film plane. Such devices need to be submicron to give resistances which can be measured easily.The figure above shows a schematic of the deposition process used to grow our heterostructures using ultra-high vacuum deposition. The left image shows the processing route (see Bell, et al., Nanotechnology 14, 630 (2003).) and the right image a micrograph of a completed device to measure the out-of-plane spin diffusion length of copper (see Leung, et al., Phys. Rev. B 72, 212409 (2005).)
This process is used to create many of the devices reported in our recent papers. |
I am also Vice-President of Hughes
