Two-dimensional van der Waals heterostructures formed by graphene and/or transition metal dichalcogenides (TMDCs), have become a captivating platform for exploring the interplay between strong electronic correlations and non-trivial band topology[1]. The recent discovery of fractional quantum anomalous Hall insulators at zero magnetic field, in a moiré heterostructure of rhombohedral pentalayer graphene aligned with hBN[2], is of intense interest as its non-Abelian anyonic excitations could be used for decoherence-free quantum computation. The project aims to study, by STM in ultra-high vacuum and low temperature (4.2 K), bilayer graphene (AB-G) and rhombohedral graphene (ABCA-G) heterostructures aligned with hexagonal boron nitride (hBN) and in proximity to TMDCs like WSe2. The research will focus on understanding the emergence of topological band structures in these materials. In addition to STM, the student will have the possibility to participate to the microfabrication of the heterostructures supervised by R. Ribeiro in the PHYNANO group, learn to work in a clear room environment and perform transport measurements.
