Abstract:
Two-dimensional (2D) materials are expected to become key components for not only electronic devices but also for energy storage applications including super capacitors and batteries as well as novel applications because of their exotic properties. Fully understanding of most of material properties needs an atomistic description from quantum mechanics.  This is also true even for explaining experimental data, especially for the systems involving nanostructures. To this end, we present the investigation of several state-of-the-art systems from first-principles calculations based on the density functional theory.  Examples will include battery applications as in Mo2C as a high capacity anode material, peculiar piezoelectric properties of various 2D systems, friction of sliding of graphene or transition metal dichalcogenide layers, and layered perovskites for solar cells.

Bio: Oğuz Gülseren is a Professor of Physics at Bilkent University, Ankara, Turkey. After graduating from Ankara Science High School, he received B. Sc. from Electronics and Electrical Engineering Department of Middle East Technical University, Ankara, Turkey (July 1986). After then, he completed his M. Sc (February1988) and Ph.D. (July 1992) in physics from Bilkent University, Ankara, where he worked on the electronic structure of low dimensional semiconductor systems. After then, he worked at SISSA-Italy (Nov. 1992 to Apr. 1995), ICTP-Italy (Nov. 1994 to Apr. 1995), Bath University-UK (Apr. 1995 to Mar. 1998), Carnegie Institution of Washington-USA (Mar. 1998 to Aug. 1999), and University of Pennsylvania and NIST-USA (Aug. 1999 to Aug. 2002). Eventually, he joined Department of Physics, Bilkent University at Sept. 2002. His current research interests include properties of nanostructures like graphene, nanotubes, nanowires, novel 2D materials, theory of self-assembly and self-organization, dye sensitized and perovskite solar cells, atomic scale friction and biomimetic adhesion from first principles calculations. He has coauthored around 85 refereed papers with an h-index 25. He has received TÜBİTAK- TWAS (Third World Academy of Science) young scientist award (2003), and İstanbul University science award (2002). He was an associate member of the Abdus Salam International Center for Theoretical Physics, ICTP, Trieste, Italy for the period 2005-2010.  He had been elected as associate member of Turkish Academy of Sciences, TÜBA between 2006 and 2012, and has been elected full member of Science Academy, Istanbul since 2012. He is the recipient of the 2016 TÜBİTAK Science Award.
