Exploring emerging quantum phenomena in 2D materials via novel optical spectroscopy. 'Novel' - since it aims for broadband energy tunability, polarization control, and high spatial-temporal resolution in one integrated setup. It also blends scanning probe techniques (AFM, KPFM, etc.) with nanofabrication. Here’s a snapshot of what it involves, plus a key publication for further details- 2D Materials (MoS2, WSe2, CGT, etc.), van der Waals heterostructures (Twistronics, Slidetronic, Moiré, etc.) Cumulative polarization in conductive interfacial ferroelectrics, Nature 612, 465, 2022 Confiocal/Micro-Optical Spectroscopy (UV-Vis, Photo Reflectance, Luminescence, Raman Spectroscopy) Excitonic signatures of ferroelectric order in parallel-stacked MoS2, Nat.
