An experimental perspective on topology and nanoelectronics in graphene and related 2D materials. — •Ivan J. Vera-Marun — The University of Manchester, UK

Topological phases in 2D systems have attracted intensive attention because of their fundamental physics and potential applications in energy efficient electronics, spintronics and quantum computation. This has been particularly true since the first theoretical prediction of a quantum spin hall state in graphene, shortly after its discovery. In this talk, we review part of the significant experimental progress achieved within the last few years on the realisation of topological phases in graphene and its heterostructures with related 2D materials, with an emphasis on nanoelectronics. Among the plethora of demonstrated approaches and effects are: the magnetic-field induced quantum spin hall state, proximity-induced spin hall effect, topological bands in bottom-up synthesized nanoribbons, up to valleytronics in manually-aligned superlattices. The latter, with the recent observation of superconductivity, pave the way for the future development of this exciting field.
