Research Interests

My current research topics under study include artificial spin/magnetic-charge ices, nano-superconductors, semimetals, nano-magnets, two-dimensional materials, magnetic semiconductors and their hybrids. The research goal is to tailor materials’ electronic or magnetic properties by nano-engineering and material hybridization. Sample fabrication methods include optical and e-beam lithography, reactive ion etching, ion milling, magnetron sputtering, e-beam evaporator etc. The characterization technique combines scanning force microscopy (AFM/MFM/EFM) imaging/patterning with transport measurements in environments of variable temperatures, three dimensional magnetic fields and gated electric fields.
