Dr. Nikolai N. Klimov is an experimental condensed matter physicist and a Project Leader (Nanoscale Fabrication and Photonics), in the Thermodynamic Metrology Group within the Physical Measurement Laboratory (PML). He received his B.S. and M.S. in Physics and Applied Mathematics from Moscow Institute of Physics and Technology (MIPT) and Ph.D. in Experimental Condensed Matter Physics from Rutgers University. His expertise is in physics and nanofabrication of semiconductor devices and structures, photonics-based nanoscale sensors and standards, and low-dimensional systems including devices based on 2D atomic crystal materials. After obtaining his Ph.D. Nikolai worked at NIST (Center for Nanoscale Science and Technology / Physical Measurement Laboratory) as a Postdoctoral Researcher on the development of gated graphene-based nanodevices, and exploring graphene’s electrical properties in a real device structures using both magneto-transport and ultra-high vacuum scanning tunneling microscopy and spectroscopy measurement techniques. Dr. Klimov’s current research is focused on the development of new field-deployable, nanophotonics-based quantum SI sensors and primary standards for temperature, pressure, vacuum, humidity, and radiation dosimetry. Within this research activity, Dr. Klimov has recently pioneered the development of on-chip integrated ultra-high resolution photonic thermometers that surpass the performance of standard platinum resistance thermometers (SPRTs), the best in class resistance temperature sensors used to disseminate the International Temperature Scale of 1990. These pioneering results show the potential of photonic thermometers to serve as a future temperature standard and replace the 150 year-old resistance thermometry. Dr. Klimov currently leads the commercialization of photonic thermometry, a collaborative effort with an industry partner. In addition, to projects related to integrated nanophotonics quantum SI metrology, Dr. Klimov is also developing grating-based devices for next-generation neutron interferometric imaging; strongly-interacting hybrid quantum systems on a chip, in which ensembles of cold atoms and cold molecules are coupled to nanophotonic devices and structures; and topologically-ordered systems for quantum information processing based on lithium niobate platform. Dr. Klimov is a recipient of NIST-ARRA Postdoctoral Fellowship (NIST/UMD) and Distinguished Associate Award (PML, NIST).
