First-Principles Theoretical Design and Analysis of Graphene Layers for Sensing Application
Abstract:
Defects in carbon-based nanomaterials such as graphene and nanotubes could modify their electronic properties. Such functionalized carbon-based nanomaterials by controlling defects might provide novel nanoelectronics applications. Thereby, graphene doped with heteroatoms have also received much attention from the viewpoint of basic nanoscience and applicable nanotechnology since heteroatom dopants can change substantially the electronic properties of graphene.
I will talk about our theoretical works of doping and adsorption effects on the stabilities and the electronic properties of graphene layers, based on the first-principles electronic-structure study within the density-functional theory.
Biography:
Dr. Yoshitaka Fujimoto received his Ph.D. degree in Engineering from Osaka University, Japan. After receiving his Ph. D., he worked at Institute of Industrial Science, the University of Tokyo, and at Center for Computational Sciences, University of Tsukuba. In 2009, he joined Department of Physics, Tokyo Institute of Technology as an Assistant Professor. His research interests include formations and electronic properties of lattice defects in surfaces and interfaces of semiconductor hetero-systems and atomic-layered materials such as graphene and h-boron-nitrides. He has published over 50 technical articles in peer-reviewed journals, reviews, book, book chapters, etc. and has served as referee of many international journals, organizer and committee in conferences.
