Bhupendra Nath Dev
Professor
Prior to joining TCG CREST, Prof. Dev was a Visiting Professor in the Department of Physics and School of Nano Science and Technology in the Indian Institute of Technology Kharagpur (2017-2020). Earlier he was a Senior Professor at Indian Association for the Cultivation of Science (IACS), Kolkata (2006-2017) and prior to that a full Professor at Institute of Physics (IOP), Bhubaneswar. He received Ph.D. in Physics (1985) from the State University of New York at Albany, USA. He worked as a Guest Scientist at Hamburg Synchrotron Radiation Laboratory (HASYLAB) at DESY in Hamburg, Germany and then returned to India and joined IOP in 1988. At IOP he set up an ion beam laboratory with ion scattering and ion implantation facilities, which include an ion microbeam facility, developed in collaboration with his alma mater State University of New York.
Prof. Dev also indigenously set up the first X-ray reflectivity and X-ray standing wave facilities in India at IOP with an 18 kW Rigaku rotating anode X-ray generator. His group has shown that the XSW technique is able to trace atomic displacement in solids with an extremely high resolution (~ 2 Angstrom). This helped understanding of ion irradiation-induced nonmagnetic to ferromagnetic transformation in multilayers.
In 2001 Prof. Dev initiated research in nano and quantum science by setting up a combined molecular beam epitaxy (MBE) and ultra-high vacuum variable temperature scanning tunneling microscopy (STM) facilities. The MBE system was based on his own design and fabricated by Omicron Nanotechnology. His group published the first work from India on MBE-grown self-organized epitaxial nanostructures and their STM and transmission electron microscopy investigations. His group worked on single-electron tunneling via scanning tunneling spectroscopy (STS).
At IACS, Prof. Dev set up a laboratory with a combined MBE-VTSTM-PEEM (photoemission electron microscopy) facility for research on quantum structures and devices. Sputter deposition facility and SQUID-VSM were added to supplement this research. Quantum dot structures of semiconductors were grown on silicon by MBE with shape control, and consequently electronic energy level control, and investigated by STS. At IACS, Prof. Dev also completed a large project on quantum structures and devices, supported by the Department of Atomic Energy.
More recently, Prof. Dev’s group discovered superconductivity in cobalt. Earlier they discovered a high-density nonmagnetic phase of cobalt in cobalt thin films on silicon. This high-density nonmagnetic cobalt is superconducting. Interestingly, in the cobalt film a self-organized superconducting(S)/ferromagnetic(F)/superconducting(S) trilayer has formed. S/F/S hybrid structures are useful in quantum information processing applications.
Prof. Dev served as a member of several programme advisory committees (PAC) of DST and SERB of Government of India and other DST expert committees [Expert Committee on Nano Science and Technology Initiative (NSTI), Expert Committee on Review of Accelerators]. As principal investigator, he has carried out international bilateral Indo-US, Indo-German and Indo-Japan collaborative research projects.
Prof. Dev’s current research interest spans superconductivity, superconducting quantum circuits, quantum control and measurement, quantum computation.
