DR. STELLA KUTROVSKAYA
"All science begins as philosophy and ends as art. To investigate means to see what everyone has seen, and to think what none else has thought. The science in the Westlake University of today is the high technology of tomorrow."
Biography
STELLA KUTROVSKAYA was born on the 21st of July in 1984 in the city of Vladimir that is about 180 km far from Moscow, Russia. She received her Master degree in Laser technics and laser technologies with honors from the Vladimir State University named after A.G. and N.G. Stoletovs in Vladimir. She received the Ph.D in Physical and Mathematical Sciences at the prestigious Moscow State University in Moscow in 2012. She joined the Vladimir State University, as a postdoctoral fellow, then becoming a Senior lecturer and eventually becoming an Associate professor. In 2016 she became a Leading researcher at the International Center for Quantum Optics & Quantum Technologies Limited Liability Company (RQC) and the Nation University of Science and technology (MISiS) in Moscow. Dr. Kutrovskaya joint the interdisciplinary group of the International Center of Polaritonics in September 2018 as a Research scientist. She was promoted to the Senior Research Scientist position at the Westlake University In March 2019.
Research
The field of expertise of Dr. Stella Kutrovskaya is on the boundary of the fundamental and applied physics. She developed a variety of research topics in the area of a laser fabrication methods and the field of hi-tech applications of nanomaterials and metasurfaces. In particular, she was synthesizing and characterizing hybrid silicon-golden nanoparticles (NPs), demonstrated the enhancement of the near-field intensity and the resonant light scattering associated with the excitation of multipole resonances in these hybrid nanoobjects. This research is highly promising for the realization of functional optical devices and metasurfaces. She also employed the method of metal film deposition for the realization of semiclassical structures that support 1D Tamm plasmons. The method was based on an electro-induced lithography providing a nanometer lateral resolution. She worked on the fabrication of nanocomposite metamaterials based on a self-assembly of titanium dioxide microtubes with encapsulated gold nanoparticles for solar cells and green energy applications. She also has been developing the new methods for the synthesis, stabilisation and deposition of ultimate one-dimensional crystals: the carbynes. Carbynes represent monoatomic carbon chains that are expected to possess unique electronic and optical properties. As they are instable in vacuum, their synthesis is challenging, and no macroscopically long free standing carbyne crystals were reported till now. Her group, initially in Russia and now at the Westlake university, China, succeeded in stabilizing carbynes with gold nanoparticles and aligning them on a solid substrate. Recently, signatures of sharp exciton resonances in carbynes that dominate their photoluminescence at cryogenic temperatures have been obtained. This is the first evidence for the existence of artificial hydrogen atoms (excitons) in monoatomic semiconductor chains. These results shed light on the physics of one-dimensional crystals and pave the way to realization of a new set of quantum nanoelectronic and nanophotonic devices including the nanometer size diodes and transistors, single and entangled photon emitters. The ICP team plans fabricating nanoelectronic networks based on linear carbon chains that will be studied with use of the high precision electronic microscopy, quantum transport measurements, cryogenic time-resolved optical spectroscopy and photon correlation measurements. The fundamental physics of monoatomic carbon chains is extremely rich, and the impact of this work on the overall development of the solid state physics may be comparable with the impact of the introduction of graphene in 2004. Due to the progress achieved very recently, the group of ICP is currently a world leader in this area. This research program will be developed in the dedicated Carbyne laboratory that is being built within the International Center for Polaritonics at the Westlake university.
