Sergei V. Dubonos is a physicist known for experimental work in nanoscale electronic systems and mesoscopic physics, with contributions to quantum transport, graphene research, Josephson junctions, and single-electron phenomena. He has collaborated with researchers from institutions such as the Russian Academy of Sciences, Delft University of Technology, Cornell University, Moscow State University, and international laboratories, participating in projects related to quantum Hall effect, superconductivity, graphene, and nanofabrication techniques.
Born in the late 20th century in the Soviet Union, Dubonos completed his undergraduate and graduate training at the Moscow Institute of Physics and Technology and pursued postgraduate work at the Institute for Solid State Physics of the Russian Academy of Sciences. During his formative years he was exposed to research traditions linked to figures such as Lev Landau, Pyotr Kapitsa, Nikolay Bogolyubov, and institutions like Kurchatov Institute and Lomonosov Moscow State University, which shaped his methodological grounding in low-temperature physics, electron transport experiments, and microfabrication techniques developed in laboratories influenced by Soviet physics and collaborations with groups at Cavendish Laboratory and Laboratoire de Physique des Solides.
Dubonos's research career spans appointments and collaborations across Russian and European institutions, including the Institute for Solid State Physics, joint projects with Delft University of Technology teams led by researchers in mesoscopic superconductivity, and visiting research positions at Cornell University in groups studying two-dimensional materials. He has worked alongside scientists associated with Bell Labs, IBM Research, Max Planck Institute for Solid State Research, and the National Institute of Standards and Technology on experimental platforms combining electron-beam lithography, scanning probe microscopy, and cryogenic measurement systems used to probe phenomena related to the quantum Hall effect, fractional quantum Hall effect, and proximity effect (superconductivity). His collaborations have linked him to researchers from Harvard University, MIT, Stanford University, University of California, Berkeley, École Normale Supérieure, and Swiss Federal Institute of Technology in Zurich.
Dubonos contributed to experimental demonstrations in nanoscale electronics, including measurements of single-electron tunneling in metallic and semiconductor devices, observations relevant to the Coulomb blockade, and studies of phase coherence in mesoscopic rings that connect to the Aharonov–Bohm effect and persistent currents explored by groups at University of Cambridge and Weizmann Institute of Science. He participated in early experimental work on graphene and related two-dimensional crystals, intersecting with developments by researchers at University of Manchester and Columbia University on charge carrier mobility, Klein tunneling, and graphene heterostructures. His experiments on hybrid normal metal–superconductor structures and Josephson junction arrays relate to concepts investigated at Argonne National Laboratory and Los Alamos National Laboratory involving Andreev reflection and phase-coherent transport. Dubonos's investigations into nanofabrication for ultrasensitive magnetometry dovetail with efforts by teams at NIST, Imperial College London, and Riken to realize nanoscale superconducting quantum interference devices and scanning SQUID microscopes. His work has informed applied research in nanoscale sensing, quantum metrology, and device architectures intersecting with initiatives at National Physical Laboratory (United Kingdom), CERN, and industrial research centers such as Intel and Samsung.
Dubonos has been recognized within national and international scientific communities through memberships, invited lectures, and collaborative grants involving organizations like the Russian Academy of Sciences, European Research Council, and national science foundations linked to the European Union and Russian Science Foundation. He has presented invited talks at conferences such as the International Conference on Low Temperature Physics, American Physical Society meetings, Materials Research Society symposia, and workshops organized by the Institute of Physics (IOP), reflecting peer recognition from communities engaged with condensed matter physics, nanotechnology, and mesoscopic physics.
