Prof. Dongbo Wang | Optical Physics | Research Excellence Award 

Harbin Institute of Technology | China

Dongbo Wang, Ph.D. is a Research Professor and Doctoral Supervisor in the School of Materials Science and Engineering at Harbin Institute of Technology (HIT), China. He received his Ph.D. in Materials Science from HIT, following an M.S. degree in Materials Physics and Chemistry  from the same institution, and a B.S. degree in Materials Science from Changchun University of Science and Technology. He has continuously served at HIT, progressing from Assistant Research Professor to Associate Research Professor, and attaining a tenured Research Professorship. Dr. Wang’s research lies at the interdisciplinary frontier of materials physics and optoelectronic engineering, with a strong focus on the design, controlled synthesis, and functional integration of low-dimensional semiconductor materials. His work covers two-dimensional bismuth chalcogenides, topological insulators, oxide heterostructures, and III–V superlattice systems. A central theme of his research is band-structure engineering and defect physics to enable high-specificity photodetectors operating across an exceptionally broad spectral range, from ultraviolet (UV) to long-wavelength infrared (LWIR). In recent years, Dr. Wang has made significant contributions to self-powered photodetectors, optoelectronic synaptic devices, and imaging systems, achieving ultra-high dynamic range and sub-femtojoule-level energy consumption. His work also extends to photothermal–photocatalytic coupling strategies for sustainable hydrogen evolution, addressing critical challenges in clean energy conversion. These advances bridge fundamental materials science with next-generation intelligent optoelectronic technologies.
