Mark McCluskey

Mark McCluskey is an American physicist and materials scientist known for his research on the fundamental properties of semiconductors and wide-bandgap materials. His work has significantly advanced the understanding of point defects, particularly the role of hydrogen, in materials such as zinc oxide and gallium nitride. McCluskey has held academic positions at institutions including Washington State University and the University of North Carolina at Chapel Hill, contributing to both education and foundational research in his field.

Early life and education

Mark McCluskey completed his undergraduate studies in physics at the University of California, Berkeley, a major research institution within the University of California system. He then pursued graduate work, earning his Ph.D. in physics from the University of Illinois at Urbana-Champaign, renowned for its programs in condensed matter physics and materials science. His doctoral research laid the groundwork for his subsequent investigations into the atomic-scale imperfections in crystalline materials, working within the influential Frederick Seitz Materials Research Laboratory.

Career

Following his Ph.D., McCluskey began his academic career as a professor in the Department of Physics and Astronomy at Washington State University in Pullman, Washington. There, he established a research laboratory focused on experimental studies of semiconductors. He later joined the faculty at the University of North Carolina at Chapel Hill, holding a position in the Department of Physics and Astronomy. Throughout his career, he has been a visiting scientist at several national laboratories, including the Lawrence Berkeley National Laboratory, collaborating with researchers like Eugene Haller. His professional service includes contributions to conferences organized by the Materials Research Society and the American Physical Society.

Research and contributions

McCluskey's primary research contributions are in identifying and characterizing point defects in semiconductors, especially wide-bandgap materials crucial for optoelectronics. He conducted pioneering studies on zinc oxide, a material with applications in ultraviolet LEDs and transparent electrodes, elucidating the properties of native defects and impurities. A major focus has been the ubiquitous role of hydrogen, demonstrating how it passivates defects and influences electrical conductivity in materials like gallium nitride, which is vital for blue laser diodes and power electronics. His experimental techniques often involve photoluminescence spectroscopy, Raman spectroscopy, and infrared spectroscopy, providing key insights referenced in foundational texts such as those by Michael A. Stroscio and Mitra Dutta. His work has implications for the development of more efficient devices in the semiconductor industry.
