Welcome

Dr. Mihir Kumar Sahoo is a Post-Doctoral Researcher at the National Institute for Materials Science (NIMS), Japan, where he investigates the optical and electrical characteristics of 2D-material single crystals integrated with metasurfaces. His research deepens the understanding of light–matter interactions in nanostructured systems, with potential applications in nanophotonics, sensing, and quantum technologies.

Previously, he worked as a Post-Doctoral Fellow at Indian Institute of Technology (IIT) Bombay, where he developed hyperbolic metamaterials based on gold pillar arrays. By combining electron-beam lithography with a novel nano-electroplating process, he established an efficient, cost-effective approach for fabricating thick metallic nanostructures without lift-off issues. This plasmonic gold pillar platform enhanced the photoluminescence of 2D TMDC monolayers (e.g., MoS₂) by harnessing the synergistic effects of surface plasmon resonance, localized plasmon resonance, and hyperbolicity. His work led to the creation of ultrasensitive biosensors capable of detecting biomolecules at extremely low concentrations.

During his doctoral studies, he focused on the fabrication, characterization, and transfer of silicon nanowire arrays for energy conversion and storage applications. His interdisciplinary collaborations across materials science, electrical engineering, and physics have equipped him with a versatile research skill set, enabling him to excel in multifaceted and cross-disciplinary environments.
