Dr. Avshish Kumar

About

Dr. Avshish Kumar has over 18 years of research experience in nanomaterials synthesis, device fabrication, and characterization. His expertise spans silicon nanowires (SiNWs), carbon nanotubes (SWCNTs and MWCNTs), 2D nanomaterials (graphene and its derivatives, MoS₂, MoSe₂, TiS₂, etc.), and metal oxides (TiO₂, SnO₂, CuO, ZnO, etc.), with applications in resistive sensing, optical (UV-Vis-IR) devices, quantum sensing, and biosensing.

His research contributions also extend to SiNWs-based devices, phase change material (PCM) based energy storage systems, electret-assisted green energy harvesting using natural wood, hydrogen generation, and microplastics removal. He has authored over 80 peer-reviewed research articles in international journals of high repute and filed 10 patents.

He has extensive hands-on experience with advanced fabrication and characterization techniques, including LPCVD, PECVD, RF sputtering, spin coating, HRTEM, FESEM, Raman spectroscopy, and X-ray diffraction (XRD). He is a life member of several professional scientific societies, including the Indian Science Congress Association (ISCA), the Electron Microscopy Society of India (EMSI), the Semiconductor Society of India (SSI), the Indian Physics Association (IPA), the Indian Physical Society, and the Society for Nano Science and Technology (SNST).

He is serving as a reviewer and editorial board member for scientific journals and has supervised 04 Ph.D. scholars to completion, with ongoing supervision of 02 Ph.D. students.
