Abstract:

Finding the contender of graphene in the field of 2D electronics and in other possible potential applications of nanotechnology has derived active search for graphene like novel structures, which do not exist in nature. As a matter of fact, the types of 3D layered materials, which make the exfoliation of their single-layer (SL) structures possible, are limited only to graphite, 2h-BN, 2h-MoS, 2h-WS, black phosphorus etc. However, most of desired electronic and magnetic properties demand materials that do not have layered allotropes. In view of the location of C, B and N elements in the Periodic Table, which constitute SL graphene and BN, questions have been raised of whether other group IV elements, group III-V, III-VI and II-VI compounds may also form SL structures. Theoretical methods have provided for quick answers to guide further experiments. These methods based on the quantum theory have reached now to a level of providing accurate predictions for chemical, mechanical, electronic, magnetic and optical properties of matter. In this talk, I will review how Periodic Table can guide the discovery and understanding of 2D materials.

Short Biography of the Speaker:

Dr. Seymur Jahangirov graduated from Nuclear Energy Engineering at Hacettepe University. He received his M.Sc. and Ph.D. from the Material Science and Nanotechnology program at Bilkent UNAM while contributing to seminal works on theoretical prediction of two-dimensional materials. After a postdoc at the Nano-Bio Spectroscopy Group in Spain, he joined Bilkent UNAM faculty as Assistant Professor. Dr. Jahangirov uses state-of-the-art computational tools based on the Density Functional Theory to discover novel low-dimensional materials with intriguing properties. Dr. Jahangirov is recipient of prestigious awards including Marie Curie Intra-European Fellowship for Carrier Development and BAGEP award from Science Academy. His research has been published in top physics journals including Nature Materials, Physical Review Letters, 2D Materials and Applied Physics Letters.
