Autor: Elena A. Zauer, Alexander B. Ershov

Publikováno v: Recent Innovations in Chemical Engineering (Formerly Recent Patents on Chemical Engineering). 15:247-260

Background: The objects of this work are silicon prismanes - new highenergy materials that can be used in various electronic, optoelectronic, thermoelectric, and biological fields and compete with traditional chemical energy carriers. However, only c

Multipolar Lattice Resonances in Plasmonic Finite-Size Metasurfaces

Autor: Artem S. Kostyukov, Ilia L. Rasskazov, Valeriy S. Gerasimov, Sergey P. Polyutov, Sergey V. Karpov, Alexander E. Ershov

Publikováno v: Photonics, Vol 8, Iss 4, p 109 (2021)

Collective lattice resonances in regular arrays of plasmonic nanoparticles have attracted much attention due to a large number of applications in optics and photonics. Most of the research in this field is concentrated on the electric dipolar lattice

Medium dependent optical response in ultra-fine plasmonic nanoparticles

Autor: Lasse K. Sørensen, Daniil E. Khrennikov, Valeriy S. Gerasimov, Alexander E. Ershov, Sergey P. Polyutov, Sergey V. Karpov, Hans Ågren

Publikováno v: Physical Chemistry Chemical Physics. 24:24062-24075

We study the influence of media on the interaction of ultra-fine plasmonic nanoparticles (≤ 8 nm) with radiation. The important role of the surface layer of the nanoparticles, with properties that differ from the ones in the inner part, is establis

Collective Lattice Resonances in All-Dielectric Nanostructures under Oblique Incidence

Autor: Anton D. Utyushev, Vadim I. Zakomirnyi, Alexander E. Ershov, Valeriy S. Gerasimov, Sergey V. Karpov, Ilia L. Rasskazov

Publikováno v: Photonics, Vol 7, Iss 2, p 24 (2020)

Collective lattice resonances (CLRs) emerging under oblique incidence in 2D finite-size arrays of Si nanospheres have been studied with the coupled dipole model. We show that hybridization between the Mie resonances localized on a single nanoparticle

On the Radio Emission of the Geminga Pulsar and RBS 1223 at the Frequency of 111 MHz

Autor: Alexander A. Ershov

Publikováno v: Bulletin of the Lebedev Physics Institute. 48:114-118

Observations on the search for pulsed radio emission from the Geminga pulsar and the close isolated neutron star 1RX J1308.6+2127 (RBS 1223) at the frequency of 111 MHz are performed. No pulsed signals are detected from both sources. Upper limits for

Elongated conductive structures in detonation soot of high explosives

Autor: I. A. Rubtsov, N. P. Satonkina, Alexander P. Ershov, A. O. Kashkarov

Publikováno v: RSC Advances. 10:17620-17626

High values of electrical conductivity are obtained at the detonation of condensed high explosives with the formula CaHbNcOd. Such values can be explained only in the framework of the contact conductivity hypothesis. In this case, the conductivity is

Nature of the Anomalous Size Dependence of Resonance Red Shifts in Ultrafine Plasmonic Nanoparticles

Autor: Lasse K. Sørensen, Daniil E. Khrennikov, Valeriy S. Gerasimov, Alexander E. Ershov, Sergey P. Polyutov, Sergey V. Karpov, Hans Ågren

Plasmonic red shifts of nanoparticles are commonly used in imaging technologies to probe the character of local environments, and the understanding of their dependence on size, shape, and surrounding media has therefore become an important target for
