Semiconductor Devices & Materials Researcher | Data Analysis, Writing and Consulting

Profile Summary

I am a PhD candidate in Physics at Fudan University, currently conducting research at the National University of Singapore. My research lies at the intersection of condensed matter physics, electronic materials, semiconductor devices, spintronics, and ultrafast spectroscopy. I have extensive experience in designing, conducting, and analyzing experimental research involving oxide thin films, two-dimensional materials, ferroelectric field-effect transistors, magnetic heterostructures, nonlinear electrical transport, and terahertz emission spectroscopy. My work has contributed to peer-reviewed publications in journals including PNAS, Advanced Science, and Advanced Electronic Materials. My research experience includes: • Ferroelectric and semiconductor devices, particularly BaTiO₃/MoS₂ ferroelectric field-effect transistors, including device fabrication, electrical characterization, memory-window analysis, subthreshold behavior, retention, endurance, and temperature-dependent measurements. • Spintronics and magnetic materials, including spin–orbit torque, magnetic heterostructures, canted antiferromagnets, and terahertz emission from magnetic thin films. • Nonlinear electronic transport in oxide thin films, including second-harmonic electrical measurements, symmetry analysis, scaling analysis, Berry-curvature-related transport, and comparison between experimental data and first-principles calculations. • Thin-film materials research, including sample design, physical interpretation of strain and interface effects, literature review, data visualization, and scientific manuscript preparation. I am proficient in scientific data analysis, technical literature review, research planning, figure preparation, and academic writing. I regularly use Origin, MATLAB, Python, COMSOL, and common scientific visualization and document-preparation tools. I also have experience interpreting device characteristics, spectroscopy data, transport measurements, and materials characterization results. Through Kolabtree, I can support projects involving: • Scientific and technical writing • Manuscript editing and academic proofreading • Literature reviews and research summaries • Data analysis and scientific visualization • Semiconductor-device and materials-science consulting • Experimental design and result interpretation • Preparation of journal figures, presentations, and technical reports • Reviewer-response preparation and manuscript revision • Technical translation between English and Chinese I have experience working with international and interdisciplinary research teams and collaborating with experimentalists and theoretical researchers. I place strong emphasis on scientific accuracy, logical structure, clear communication, and reproducible analysis. I can work with both academic researchers and technology companies on projects related to semiconductor devices, functional materials, condensed matter physics, spintronics, and scientific communication.
