Abstract: Since its discovery, graphene has been recognized for its exceptional physical, electronic and optical properties. While the lack of an energy gap has limited conventional device applications, our research has focused on its sensing abilities. Graphene is an attractive material to sense adsorbates which impact carrier concentration and leads to measurable variations in conductivity. Here, we report on epitaxial graphene sublimated from SiC substrates as the material of choice for sensor development, focusing on underwater, sulfur and biological sensors. In addition, the use of graphene to grow remote epitaxial films to impact power electronics and quantum science applications will be presented.
Bio: Dr. Rachael Myers-Ward is an electrical engineer in the High Power Electronics Branch/ Power Electronic Materials Section at the U.S. Naval Research Laboratory. She received a Ph.D. in electrical engineering and B.S. and M.S. degrees in chemical engineering from the University of South Florida. Her research interests include epitaxial growth of SiC via chemical vapor deposition for high power/high voltage device applications and quantum science, methods to reduce extended and point defects in SiC epitaxial layers, and synthesis of epitaxial graphene for sensor applications. Dr. Myers-Ward has organized 10 conference symposia and is on the AVS Board of Directors and Governance Committee. Her scientific contributions have led to 136 publications with an H-index of 36, one book chapter, and 10 patents.
