Roman Gorbachev: New materials for van der Waals heterostructures

In the last three years, a novel field has emerged which deals with structures and devices assembled layer-by-layer from various atomically-thin crystals. These new multi-layer structures have proved to be extremely versatile, showing exceptional electronic and optical properties, new physics and new functionality. This is mostly due to the fact that each atomic layer can be chosen among many different materials including metals, semiconductors, superconductors or even topological insulators. 
In this talk I will review recent progress and discuss new additions to the 2D material family, their fabrication and transport properties. I will present our newest results on atomically thin crystals of InSe – material that hasn’t been sufficiently studied before and now shows outstanding optical and electronic properties. Other materials, such as black phosphorus, niobium diselenide and gallium selenide will be discussed with specific attention paid to fabrication and their chemical stability.

Roman Gorbachev received his B. Sc. from the Novosibirsk State University (Russia), his PhD from University of Exeter (UK). He moved on to postdoc at Manchester University and has received Royal Society University Research Fellowship in 2014. Since 2015 Roman is Senior Research Fellow at Manchester University.
