With more than 15 years of university-level teaching and research experience in Vietnam and Taiwan, he has developed a strong profile as an educator, researcher, and mentor in materials science, thin-film technology, nanotechnology, and applied physics.
Dr. Le earned his Ph.D. in Materials Science and Engineering from National Chiao Tung University (NCTU), Taiwan, in July 2014. He subsequently conducted postdoctoral research at NCTU, focusing on topological insulator thin films and their magnetotransport and ultrafast dynamic properties. From 2016 to 2023, he served at Can Tho University of Medicine and Pharmacy (Vietnam), where he was promoted to Associate Professor in Physics, held leadership roles as Department Chair and Vice Dean, and supervised numerous graduate students. He was also a visiting associate professor at National Yang Ming Chiao Tung University (NYCU) before joining MCUT.
Over the past 2.5 years at MCUT, Dr. Le has established and expanded the PHL Research Group, developing well-equipped laboratory facilities for thin-film fabrication, nanomaterial synthesis, and photoelectrochemical characterization. He currently supervises or co-supervises four Ph.D. students and four master’s students, with several students nearing graduation and transitioning into doctoral programs.
Dr. Le’s research interests include:
- Nanomaterials for photocatalysis and photoelectrochemical water splitting, energy conversion and storage (HER, OER, electrochemical sensing, supercapacitors);
- Thermoelectric materials and metal oxide/nitride thin films, developed primarily by magnetron sputtering, and the study of their structural, morphological, compositional, electrical, optical, nanomechanical, and functional properties.
As an IIPP mentor, Dr. Le is committed to providing international interns with hands-on research training, close supervision, and an inclusive academic environment that supports both undergraduate and graduate students in developing experimental skills, scientific thinking, and international research experience.

The PI’s laboratory, in close collaboration with the Center for Plasma and Thin Film Technologies at Ming Chi University of Technology (MCUT), provides a well-equipped and supportive research environment for IIPP international internship students. By combining the PI’s dedicated laboratory space with shared preparation rooms and central facilities at the Center, interns will have access to all essential infrastructure required for nanomaterial synthesis, thin-film fabrication, and electrochemical characterization.
The laboratory supports a wide range of nanomaterial synthesis techniques, including hydrothermal and solvothermal synthesis, sol–gel processing, spin coating, chemical reduction, electrodeposition, and electrochemical exfoliation. Key in-lab equipment available for student use includes ten hydrothermal autoclaves (100 mL), a laboratory oven (72 L, up to 250 °C), a muffle furnace (up to 1200 °C), a centrifuge (6000 rpm, 15 mL), a vacuum/inert-gas annealing system (up to 1200 °C), two precision balances (maximum 240 g, 0.0001 g resolution), a nanomaterial filtration system with aspirator pump (PVDF 0.22 µm), an electrochemical workstation (Biologic SP-200), and a photoelectrochemical (PEC) measurement system.
All necessary consumables—including chemicals, solvents, glassware, substrates, and sputtering targets—will be provided during the internship period. In addition, the PI’s laboratory hosts multiple experienced Ph.D. students who actively assist with hands-on training, day-to-day laboratory guidance, and safe experimental operation, creating a friendly and collaborative learning environment for visiting interns.
While electrochemical and photoelectrochemical measurements are primarily conducted in the PI’s laboratory, advanced materials characterization is carried out using the shared instrumentation of the Plasma and Thin Film Technologies Center. These facilities include X-ray diffraction (XRD), SEM-EDS, UV–Vis spectroscopy, FTIR, XPS, high-resolution TEM (HRTEM), and nanoindentation, with guidance provided by the PI and senior group members.
Overall, the laboratory offers a safe, well-supported, and resource-rich research setting, enabling IIPP interns to gain valuable hands-on experience in nanomaterials and thin-film research within a structured mentoring framework.

Research topics
Topic 1
Title: NiCo₂O₄ Nanostructured Films for Photocatalytic Degradation, Antibacterial Activity, and Photoelectrochemical Water Splitting
Description:
In this project, NiCo₂O₄ nanostructured films with various morphologies (e.g., nanosheets and nanorods) will be synthesized on ITO glass and Ni foam substrates using the hydrothermal method. Growth parameters such as precursor composition, pH, hydrothermal temperature, and reaction time will be systematically adjusted to tailor the morphology and surface area of the films. Structural, morphological, and chemical properties will be characterized using XRD, SEM-EDS, HRTEM, FTIR, XPS, and UV–Vis spectroscopy. Photocatalytic activity will be evaluated via the degradation of methylene blue and Rhodamine B. Photoelectrochemical (PEC) water-splitting performance will be investigated using LSV, EIS, and photocurrent stability (I–t) measurements. In addition, antibacterial activity will be assessed using E. coli (ATCC 25922) under dark and weak UV–vis light conditions.
Topic 2
Title: Au–Ag Co-decorated TiO₂ Nanostructured Films for Photocatalytic, Antibacterial, and Photoelectrochemical Applications
Description:
TiO₂ nanotube arrays and TiO₂ nanowire/nanotube structures will be fabricated via anodic oxidation of Ti foil in an ethylene glycol–based electrolyte containing NH₄F and water. Plasmonic Au and Ag nanoparticles, as well as Au–Ag co-decorated systems, will be deposited onto TiO₂ nanostructures through a combined photodeposition and thermal annealing process. The effects of noble metal type, loading amount, and co-decoration on optical, structural, and functional properties will be systematically investigated. Characterization will be performed using XRD, SEM-EDS, HRTEM, FTIR, XPS, and UV–Vis spectroscopy. Photocatalytic dye degradation, PEC water splitting performance, and antibacterial activity against E. coli will be evaluated and compared.
Topic 3
Title: Mass Production of Graphene and Graphene Quantum Dots via Electrochemical Exfoliation for Photocatalytic and PEC Applications
Description:
This project focuses on the electrochemical exfoliation of graphite to achieve scalable and low-cost production of graphene and graphene quantum dots (GQDs). The effects of electrolyte composition, applied voltage, and exfoliation time on yield and material quality will be investigated. The obtained graphene and GQDs will be characterized using SEM, TEM, UV–Vis spectroscopy, FTIR, and Raman spectroscopy. These carbon nanomaterials will then be integrated with TiO₂ or other metal oxides to form composite photocatalysts and photoelectrodes. Their roles in enhancing light absorption, charge separation, and electron transport will be evaluated through photocatalytic dye degradation and photoelectrochemical water-splitting measurements.
Topic 4
Title: Carbon–TiO₂ Nanocomposites for Solar-Driven Seawater Desalination
Description:
Carbon nanomaterials will be produced from graphite rods and combined with TiO₂ nanopowder to form C–TiO₂ nanocomposites with different mass ratios. The nanocomposites will be coated onto paper-based membranes and applied to solar-driven desalination. Water evaporation performance will be evaluated by monitoring mass change under UV–vis irradiation. An infrared camera will be used to study surface temperature distribution and photothermal heating behavior, allowing correlation between composition, heat generation, and evaporation efficiency.
