Rare-earth orthoferrites are a promising platform for antiferromagnetic spintronics with a rich variety of terahertz spin and lattice dynamics phenomena. For instance, it has been experimentally demonstrated that the light-driven optical phonons can

Strain in 2D TMDCs induced by metal-assisted exfoliation from the polyvinilalcohol-covered substrate

Autor: Kamenskaya, T. A., Eliseyev, I. A., Davydov, V. Yu., Kuntsevich, A. Yu.

We have modified the metal-assisted transfer technique to obtain large-area few-layer flakes from transition metal dichalcogenides bulk crystals by introducing an initial stage - exfoliation of the bulk crystal onto an intermediate substrate, specifi

Direct observation of split-mode exciton-polaritons in a single MoS$_2$ nanotube

Autor: Galimov, A. I., Kazanov, D. R., Poshakinskiy, A. V., Rakhlin, M. V., Eliseyev, I. A., Toropov, A. A., Remskar, M., Shubina, T. V.

A single nanotube synthesized from a transition metal dichalcogenide (TMDC) exhibits strong exciton resonances and, in addition, can support optical whispering gallery modes. This combination is promising for observing exciton-polaritons without an e

Laser-induced Demagnetization in van der Waals $XY$- and Ising-like Antiferromagnets NiPS$_3$ and FePS$_3$

Autor: Kuntu, D. V., Arkhipova, E. A., Shelukhin, L. A., Mertens, F., Prosnikov, M. A., Eliseyev, I. A., Smirnov, A. N., Davydov, V. Yu., Mañas-Valero, S., Coronado, E., Cinchetti, M., Kalashnikova, A. M.

Publikováno v: Phys. Rev. Materials 8, 014408 (2024)

The critical behaviour of laser-induced changes in magnetic ordering is studied experimentally in two-dimensional zigzag antiferromagnets $XY$-like NiPS$_3$ and Ising-like FePS$_3$. To examine laser-induced dynamics in flakes of these compounds, we e

State-of-the-art and prospects for intense red radiation from core-shell InGaN/GaN nanorods

Autor: Evropeitsev, E. A., Kazanov, D. R., Robin, Y., Smirnov, A. N., Eliseyev, I. A., Davydov, V. Yu., Toropov, A. A., Nitta, S., Shubina, T. V., Amano, H.

Core-shell nanorods (NRs) with InGaN/GaN quantum wells (QWs) are promising for monolithic white light-emitting diodes and multicolor displays. Such applications, however, are still a challenge because intensity of red band is too weak as compared wit
