Summary
Led advanced materials research focused on the optical properties of high-entropy alloy thin films, integrating multidisciplinary characterization to drive novel discoveries.
Highlights
Discovered tunable second-harmonic generation in centrosymmetric metallic alloys, achieving 4-6x enhancement through compositional engineering, with findings under review by Nature Communications.
Achieved precise control of electrical resistivity (89-324 μΩ·cm) with a near-zero temperature coefficient (-2.86 ppm/K) in high-entropy alloy thin films, published in Applied Materials Today (2025).
Established atomic-scale structure-property relationships by integrating TEM/STEM, SEM/EBS, XRD, and optical spectroscopy (PL, SHG, UV-Vis) to identify critical roles of interface structures and compositional modulation.
Expertly synthesized thin films using magnetron sputtering (DC/RF co-sputtering, reactive sputtering, HiPIMS) and MBE epitaxial growth, demonstrating compositional control of alloys, oxides, and nitrides.
Operated UHV multi-chamber systems within clean room environments for over 3 years, ensuring high-purity fabrication conditions.
Authored 3 peer-reviewed research papers as first author and currently have 3 additional manuscripts in preparation, demonstrating strong research output.
Collaborated effectively with international academic partners from the University of Grenoble (SIMAP), University of Minho (Portugal), and ITMO University (Russia).
