Dr. Muhammad Sulaman is an Associate Professor (Research) at the School of Science, Minzu University of China, Beijing, where he is affiliated with the Optoelectronics Research Center. He received his Ph.D. in Physics from the Beijing Institute of Technology (BIT), China, and subsequently conducted postdoctoral research at BIT in the fields of optics, photonics, and advanced functional materials. His research interests encompass semiconductor optoelectronic devices, self-powered photodetectors, quantum dots, two-dimensional materials, perovskites, nanostructured materials, and interface-engineered heterojunctions for broadband photodetection. His current research particularly focuses on solution-processed UV–visible–NIR/SWIR photodetectors, colloidal quantum-dot/2D-material hybrid heterostructures, bulk heterojunctions, charge-transport and interface engineering, and device-physics simulations. His work combines experimental device fabrication and characterization with density functional theory (DFT), TCAD, and optical simulations to understand charge generation, separation, transport, recombination, and light–matter interactions in emerging optoelectronic systems. Dr. Sulaman has published approximately 85 SCI-indexed research and review articles, including more than 40 as first or corresponding author, and his work has received over 2,500 citations with an h-index of approximately 30. His research has appeared in journals covering advanced materials, photonics, nanotechno
