Scientific Interests and Work

High pressure and semiconductor physics.

Professor Matthew D. McCluskey has a broad research background in high-pressure and semiconductor physics. The primary focus is on materials that are important for optoelectronic applications, such as wide-bandgap semiconductors. The McCluskey group is also developing new microscopy techniques.


Dr. McCluskey performed his research for his Ph.D. primarily at the Lawrence Berkeley National Laboratory, under Prof. Eugene Haller (Materials Science and Engineering). He studied the behavior of hydrogen vibrational modes under hydrostatic pressures using Fourier transform infrared (FTIR) spectroscopy and diamond-anvil cells. Dr. McCluskey then worked as a postdoctoral research associate at the Xerox Palo Alto Research Center (PARC), under Dr. Noble Johnson from 1997-1998. His research concentrated on the material properties of gallium nitride-based semiconductors. In 1998, he joined the Department of Physics at Washington State University as an Assistant Professor. In 2009, he was promoted to Professor.
