Starting with graphene, 2D materials have been of interest for electronics and optoelectronics. In the last few years, there is a renewed interest in topological and superconducting properties of 2D materials as the systems offer unique experimental knobs; I will show some examples in this broad category.

High-temperature superconductors are important for potential applications and for understanding the origin of strong correlations. BSCCO, a van der Waals high-temperature superconducting material (Tc of 85 K), offers a platform to probe the physics down to a unit-cell. Modifying superconductivity in HTS locally, on a small length scale, is of immense interest for superconducting electronics. We develop a simple route to modify superconductivity locally by depositing metal on the surface of a few unit-cell thick BSCCO.  This opens up avenues for new superconducting devices.
