Dr. A. Victor Adedeji is an assistant professor of physics in the department of Chemistry, Geology, and Physics. His research interest includes: development of contact metallization scheme for Wide Band Gap (WBG) semiconductor microelectronics useful for special applications in harsh environment; and the deposition and characterization of thin films for "smart window" applications.

Research Interest: Include fabrication and characterization of micro- and nano-electronic contacts (both Ohmic & Schottky) on Wide Band Gap (WBG) semiconductor (SiC, GaN, diamond etc.) for applications in extreme environment. WBG semiconductors are advanced materials with intrinsic properties that make them suitable for high power and high frequency device fabrication and for devices that are able to survive in high temperature and high radiation environment. It is important to develop contacts that can survive in these extreme conditions as well. Otherwise, the rapid failure of contact metallization can cause devices to fail quickly. We are also interested in developing and characterizing multilayer thin films for “smart window” application. These films are chromogenic, the transmitted radiation through them depend on ambient temperature (thermochromic) and applied voltage (electrochromic). They are important for efficient energy consumption in modern buildings.
