Transport phenomena in emerging quantum nano-devices: Our group works in the area of quantum transport of nano-devices at ultra-low temperatures and high magnetic fields using reduced dimensions like two-dimensional graphene, two-dimensional transition metal dichalcogenides, topological insulator, one-dimensional nanowires and their hybrids. Our pioneering transport studies on emerging two-dimensional materials are followings: Transport properties of graphene-Moiré superlattices; Compressibility studies to unravel electron interactions in graphene quantum-Hall systems; Unconventional Andreev reflection at the graphene-superconductor junction; Anomalous coulomb drag in dimensionally mismatched heterostructures; Quantum noise to unravel the edge dynamics in ultra-clean graphene p-n junction; Thermal transport in integer and fractional quantum Hall states of graphene; Light-matter interaction in atomically thin p-n junction.
