Topology and Quantum Transport in Emerging 2D Materials

Abstract

In this talk, I will present our ongoing research on quantum transport in emerging two-dimensional (2D) materials beyond graphene. I will first introduce the MISFIT layered compounds, a unique class of natural van der Waals heterostructures, and discuss our recent investigations into their structural, electronic, and transport properties. In the second part, I will demonstrate how focused ion beam (FIB) can be employed to study the out-of-plane transport in these 2D materials. As a case study, I will demonstrate how we can correlate the observation of quantum oscillations with periodic lattice modulations in the FIB-microstructured devices of a topological nodal-line semimetal, SnTaS₂. I will also present our recent efforts on ionic liquid gating of 2D insulators. Lastly, I will conclude by introducing our newly established 2D materials fabrication and low-temperature quantum transport measurement facility at MPI CPfS.
