Prof. Elena Besley
Summary
The class of 2D materials has been dominated by well-studied structures such as conducting graphene, semiconducting chalcogenides, and insulating BN. We will discuss how assemblies of molecular organic networks on surfaces can offer unlimited flexibility in geometries, electronic structure, and chemical functionality, and could offer another leap in the design of 2D materials.
Supramolecular chemistry examines weak, often reversible, non-covalent interactions between molecules which include van der Waals forces, electrostatic effects, hydrogen bonding, and metal coordination. Such van der Waals heterostructures can be integrated with few-layer graphene contacts to form simple devices such as a molecular/two-dimensional hybrid tunnel diode.

Prof. Elena Besley, FRSC, obtained her PhD in Physics and Mathematics (2000) from St. Petersburg State University, Russia. In 2000 she held a Royal Society/NATO postdoctoral research fellowship at the Queen's University of Belfast. There followed postdoctoral research appointments in Chemistry at the Universities of Nottingham, Sussex and Cambridge. In 2007 Elena was awarded a Royal Society UK Relocation Fellowship and moved back to Nottingham. She was appointed to a Lecturer in Theoretical and Computational Chemistry at Nottingham in 2011, followed by promotion to an Associate Professor in 2014 and a Professor in 2015. To date, Elena has published a total of 160+ scientific papers, with an h-index of 41, and has served as Editor for the RSC monograph Computational Nanoscience. Elena has been a recipient of numerous academic fellowships and awards, including most recently a Lifetime Achievement Award from the Electrostatics Society of America. Since 2021, Elena has been an Associate Editor of the ACS journal Nano Letters.
