Professor Sankar Dhar has joined Physics department of SNU in 2012. He obtained his Ph.D. degree in Physics from I.I.T. Kanpur in 1997 and master degree in physics from Jadavpur University in 1989. After receiving DST young scientist award in 1997, he joined as a post-doctoral fellow and later (1998-2003) worked as a scientist and group leader of the ion beam based materials research program in II. Physics Institute at the University of Göttingen, Germany. Later in 2003, he joined as a leader of ion beam based materials research program of the Accelerator center at the University of Maryland, College Park, USA. Prior to joining SNU, Prof. Dhar worked in the National university of Singapore (NUS) from 2007 as a senior scientist for building and developing the NUSNNI-NanoCore, an integrated new nano-materials research center. He is enthusiastic about teaching and his general research interests include the growth of functional thin films/nano-materials and manipulating their structural, electronic, magnetic, and optical properties using pulsed laser and ion beam. He has filed several patents and published over 120 articles in referred international journals and books.
My primary interest is on the functional oxide materials at sub-500 nm thickness range, where fascinating science has manifested over the last decade. New oxide materials with exotic properties and functions for the next generation electronic devices are being explored by growing thin epitaxial 2D/3D films, nano-materials, and hetero-structures using pulsed laser, pulsed electron and sputter deposition and ion implantation of surfaces. I am currently focused on transparent oxide layers, homo/hetero junction, bandgap engineering, 2D layer-oxide interactions, strain engineering at sharp atomic interfaces, defect induced ferromagnetism and resistive switching. Moreover, I use energetic ion beam for material characterizations and modifications via impurity doping, atomic mixing, alloying, nano-structuring, and solid state catalysis processes.search Interest
