Main research and technological activities

My research focuses on the design, synthesis, fabrication, characterization, and optimization of advanced nanomaterials and micro/nanoelectronic devices for energy conversion, optoelectronics, nanophotonics, and sustainable technologies. My work integrates materials science, nanotechnology, device engineering, and interface physics to develop high-performance functional materials with tailored optical, electrical, thermal, and electrochemical properties.
My research interests span semiconductor nanomaterials, quantum dots, thin-film technologies, carbon-based nanomaterials, hybrid nanocomposites, and plasmonic nanostructures. I develop solution-processed and thin-film devices for photodetection, energy harvesting, thermoelectric conversion, and advanced sensing applications. Current activities include self-powered quantum-dot photodetectors operating from the visible to the near-infrared (NIR), with emphasis on charge transport, interface engineering, broadband photoresponse, low-noise operation, and device reliability.
Another major research direction is the development of advanced thermoelectric materials and hybrid energy systems for waste-heat recovery and self-powered electronics. My work includes ionic and electronic thermoelectric materials, conductive polymers, nanocomposites, bio-derived functional materials, and low-dimensional thin films, aiming to improve energy conversion efficiency through materials engineering and nanoscale interface design.

I also investigate multifunctional nanomaterials for energy storage, photoelectrochemical systems, and optoelectronic devices, including carbon nanostructures, graphene-based materials, MXene composites, metal chalcogenides, metal oxides, and lead-free semiconductor nanomaterials. My research combines experimental materials synthesis with advanced device fabrication and comprehensive structural, optical, electrical, and electrochemical characterization.
My technical expertise includes cleanroom micro- and nanofabrication, solution processing, spin coating, thin-film deposition, photolithography, dry etching, and electrical contact fabrication. I routinely employ Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–Vis–NIR spectroscopy, ellipsometry, impedance spectroscopy (EIS), current–voltage characterization, transient photoresponse analysis, and low-noise electrical measurements to establish structure–property relationships in functional nanomaterials.
Through interdisciplinary collaborations, I aim to translate fundamental nanoscience into scalable technologies for sustainable energy systems, intelligent sensors, next-generation optoelectronic devices, and advanced functional materials.
