Executive Summary : | The study focuses on the observation of topological quantum capacitance in strongly-correlated van der Waals (vdW) systems, which are crucial for low-power nanoelectronics and valleytronics. These phases are identified and protected by spin-momentum locking phenomena, and the inclusion of magnetic ordering can break time-reversal symmetry (TRs) and create topologically non-trivial states. This leads to novel phenomena such as quantum spin-Hall effect, quantum anomalous Hall effect, giant magneto-conductance effect, and topological phase transition. Three-dimensional (3D) topological insulator (TI) allows Landau quantization and quantum Hall phenomena at weak magnetic fields. The study aims to understand topological quantum capacitance through interfacial phenomena via magnetic proximity effect in two-dimensional (2D) quantum systems. By probing magnetocapacitance oscillation by constructing interface effects, the study will open new avenues in topology and quantum effects. The project will focus on establishing the interfacial phenomena via magnetic proximity effect on strongly-correlated 2D vdW heterostructure. |
