Structural phase transitions in double perovskite crystals studied by Brillouin light scattering
D. O. Horiachyi, M. O. Nestoklon, I. A. Akimov +5
Inorganic lead-free double perovskites represent particular interest as non-toxic and stable material platform for optoelectronic applications. Here, we employ Brillouin light scat…
Spin dynamics of excitons and carriers in mixed-cation MAFAPbI perovskite crystals: alloy fluctuations probed by optical orientation
B. F. Gribakin, N. E. Kopteva, D. R. Yakovlev +5
Optical spin orientation measured by time-resolved photoluminescence provides a powerful tool to probe the spin dynamics of excitons and charge carriers in perovskite semiconductor…
Efficient launch of shear phonons in photostrictive halide perovskites
Dmytro Horiachyi, Mikhail O. Nestoklon, Ilya A. Akimov +10
Optical generation of transverse coherent phonons by femtosecond light pulses is appealing for high-speed sub-THz active control of material properties. Lead-free double perovskite…
Effect of crystal symmetry of lead halide perovskites on the optical orientation of excitons
Nataliia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +8
The great variety of lead halide perovskite semiconductors represents an outstanding platform for studying crystal symmetry effects on the spin-dependent properties. Access to them…
Transverse magnetic routing of light emission in hybrid plasmonic-semiconductor nanostructures: Towards operation at room temperature
L. Klompmaker, A. N. Poddubny, E. Yalcin +8
We study experimentally and theoretically the temperature dependence of transverse magnetic routing of light emission from hybrid plasmonic-semiconductor quantum well structures wh…
