Light Scattering From an Atomic Array Trapped Near a One-Dimensional Nanoscale Waveguide: a Microscopic Approach
V. A. Pivovarov, A. S. Sheremet, L. V. Gerasimov +4
The coupling of atomic arrays and one-dimensional subwavelength waveguides gives rise to in- teresting photon transport properties, such as recent experimental demonstrations of la…
Unified mechanism of the surface Fermi level pinning in III-As nanowires
P. A. Alekseev, M. S. Dunaevskiy, G. E. Cirlin +4
Fermi level pinning at the oxidized (110) surfaces of III-As nanowires (GaAs, InAs, InGaAs, AlGaAs) is studied. Using scanning gradient Kelvin probe microscopy, we show that the Fe…
Ultracentrifugation for ultrafine nanodiamond fractionation
S. V. Koniakhin, N. A. Besedina, D. A. Kirilenko +2
In this paper we propose a method for ultrafine fractionation of nanodiamonds using the differential centrifugation in the fields up to 215000g. The developed protocols yield 4-6 n…
Enhancement of inherent Raman scattering in dielectric nanostructures with electric and magnetic Mie resonances
Kristina Frizyuk, Mehedi Hasan, Alex Krasnok +2
Resonantly enhanced Raman scattering in dielectric nanostructures has been recently proven to be an effcient tool for developing nanothermometry and experimental determination of t…
Dielectric nanoantenna as an efficient and ultracompact demultiplexer for surface waves
Ivan S. Sinev, Andrey A. Bogdanov, Filipp E. Komissarenko +7
Nanoantennas for highly efficient excitation and manipulation of surface waves at nanoscale are key elements of compact photonic circuits. However, previously implemented designs e…
Adaptive Filtering to Enhance Noise Immunity of Impedance and Admittance Spectroscopy: Comparison with Fourier Transformation
Daniil D. Stupin, Sergei V. Koniakhin, Nikolay A. Verlov +1
The time-domain technique for impedance spectroscopy consists of computing the excitation voltage and current response Fourier images by fast or discrete Fourier transformation and…
