Spring '23 Department Seminars with Dr. Seymur Jahangirov
Title: Variations on a Theme in B Flat
Speaker: Dr. Seymur Jahangirov, Assistant Professor
Institute of Material Science and Technology, Bilkent University
Date: May 2, 2023, Tuesday
Place: Departmental Seminar Room (SB-Z14)
The synthesis of graphene sparked a “gold rush” to find other 2D materials with intriguing properties. Our early theoretical work on predicting silicene, germanene, and other 2D materials inspired experimental studies that resulted in the synthesis of these materials on specific substrates. Recently, our studies have focused on predicting novel 2D materials that are composed (solely or partially) of boron atoms, creating an excellent opportunity for wordplay used in the title of this talk. We will start by briefly introducing our main tool, Density Functional Theory, and how it helps reconcile a physicist’s many-body perspective with a chemist’s orbital view. Then, we will describe the novel boron structures, with an emphasis on our study of 2D diboron-dinitride, which has a direct band gap at around 1.7 eV. This property is highly tunable by strain engineering, making this material an excellent candidate for optoelectronic applications.
