Prof. Raychaudhuri obtained his M.Sc from IIT,Kanpur (1975) and Ph.D from Cornell University (1980). He had post-doctoral experience at the Max Planck Institute (FKF),Stuttgart as an Alexander von Humboldt Fellow (1980-1982). Prior to joining S.N. Bose National Centre for Basic Sciences in 2004 , he worked as a Professor in Indian Institute Science (IISc), Bangalore and as Director, National Physical Laboratory (NPL), New Delhi.
His research interest covers a broad canvas of problems in condensed matter physics and materials physics. This includes physics of glassy states, metal-insulator transition in oxides, physics of High Tc superconductors and colossal magnetoresistance. His research activities encompass synthesis of materials of different kinds, fabrication of nano devices and physical measurements done down to low temperatures in high magnetic fields using a variety of techniques involving electrical, magnetic and optical measurements as well as scanning probe techniques and electron microscopy.
His current research mainly focuses on nanomaterials that include nanofabrications using nanolithography techniques such as use of electron-beam and ion-beam lithography for fabrication of single nanowires based devices. These single nanowires devices are used for studying new physics and making ultra-sensitive radiation and charge detectors. The study of basic physics issues involve physics of size reduction, enhanced photo response in nanowires, 1/f noise and resistance fluctuations in nanowires .
His group (in IISc and SNBNCBS) had graduated more than 30 Ph.D students who are now established researchers/academics/professionals in India and abroad. His research work is widely cited. He is a recipient of the Shanti Swarup Bhatnagar Prize in Physical Sciences and is a Fellow of all the Science academies in India.
Professor AKR serves in a number of national committees that include Science and Engineering Research Board (SERB) and Programme Advisory Committee (PAC) on Solar energy research initiative of the Department of Science and Technology, Gov of India. He had been a member of the Science and Engineering Research Council (SERC) of the Department of Science and Technology and chaired the PAC on condensed matter physics and materials science. He also chaired the FIST advisory committee of DST on physical sciences. He has served as the member of Board of Governors (BOG) of IISER , Pune and IIT, Kanpur.
