About
Materials science PhD candidate with hands-on experience in advanced materials engineering & microscopy characterization, particularly SEM, FIB-based TEM specimen preparation, TEM/STEM, EDS and XRD. Experienced in linking microstructure, crystallography and composition across bulk and thin-film materials, supported by materials synthesis and complementary physical-property measurements. Research experience spans Bi2Te3-based layered materials, defect engineering and structure-property relationships, with a strong record of peer-reviewed publication and collaborative laboratory work.
Experience
Ph.D. Candidate (Full time) - Queensland University of Technology - Brisbane, Australia
(2023-07)
- Synthesised Bi2Te3-based bulk materials by melting and SPS method and thin films by PVD system.
- Microstructure characterization and phase identification by XRD, SEM with EDS and TEM/STEM with EDS, including preparation of electron transparent specimens by FIB and PIPS.
- Analysed nanoscale defects, interfaces, composition and crystallography to relate processing conditions to material structure and behaviour.
- Thermoelectric performance measurement by ZEM-3, LFA, STPM and LaserPIT.
Research Assistant (Casual) - The University of Queensland - Brisbane, Australia
(2023-02 - 2023-06)
- Modified TiO2 by NaBH4 reduction and by photo-deposition method.
- Characterized the materials by XRD and UV-Vis, XPS, TGA and FT-IR.
- Estimated the performance of Au-Blue-TiO2 for oxidative coupling of methane via GC.
Quality inspector (Internship) - Suzhou Highfine Biotech Co., Ltd. - Suzhou, China
