Abstract: Since the exfoliation of graphene two-dimensional materials have been one of the mostly investigated systems because of their emerging and exotic properties, and they are expected to become key components for novel applications. Fully understanding of most of material properties needs an atomistic description from quantum mechanics. In this respect, we present the investigation of several state-of-the-art 2D systems from first-principles calculations based on the density functional theory. Examples will include the optical properties of 2D heterostructures formed by graphenelike ZnO and MgO monolayers for optoelectronic applications, fundamental understanding of twisted bilayer graphene and essentials for the description for magnetic properties of Mxenes.
Bio: Oğuz Gülseren is a Professor of Physics at Bilkent University, Ankara, Turkey. After graduating from Ankara Science High School, he received a 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 that, 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 the 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 co authored more than 120 refereed papers with an h-index 37. 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, the most prestigious award for science in Türkiye.
