Research Projects

I am currently studying several novel semiconductor systems using various synchrotron-based techniques, including X-ray absorption and emission spectroscopy. Recently, this has included materials used in phosphor-conversion based LEDs, transition and post-transition metal oxides and semiconductor nitride systems. This work has lead to the development of new capabilities, including a technique to measure depth profiles of defects in semiconductors via X-ray excited optical luminescence.  [Abstract] This work has been featured by the Canadian Light Source.
