Our primary research focuses on developing new quantum materials based on color centers in wide bandgap semiconductors and two dimensional materials for applications in quantum sensing and quantum information processing. Four projects we are pursuing now:
-
Diamond nanoscale mapping of chiral spin textures, spin/charge current, spin torque effect in magnetic thin films/multilayers, 2D magnetic films, oxide heterostructures, and topological insulators.
-
Defect discovery and spectroscopy in two dimensional materials (TMDs, hBN) and wide bandgap semiconductors (GaN, SiC, ZnO): studying the spin and optical properties of the defects, developing new applications based on their quantum properties.
-
Exploring magnetic waveguides/cavities for coupling distant spin-qubits in diamond and SiC for scalable quantum networks
-
Hybrid nanophotonic materials: Coupling color centers to plasmonic nanostructures for enhanced quantum optical properties.
These research activities are mainly experimental and involve spectroscopy (optical detected magnetic resonance, fluorescence, magneto-optics), microscopy (TEM, AFM, SEM, Near-field, Confocal, Far-field, etc.), RF/MW electronics (PCB and stripline design, RF/MW equipment and pulse control), materials processing (ion beam implantation, irradiation, high temperature annealing, acid clearing, etc.), and device fabrication (E-beam, Evaporation, etching, etc.).
