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…
Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…
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…
Coherent spin dynamics of electrons and holes photogenerated with large kinetic energy in lead halide perovskite crystals
Evgeny A. Zhukov, Dmitri R. Yakovlev, Erik Kirstein +4
The coherent spin dynamics of electrons and holes are studied in a FA0.9Cs0.1PbI2.8Br0.2 perovskite bulk crystal, using time-resolved Kerr ellipticity in a two-color pump-probe sch…
Landé g-factors and spin dynamics of charge carriers in CuCl nanocrystals in a glass matrix
Dennis Kudlacik, Evgeny A. Zhukov, Dmitri R. Yakovlev +7
The spin properties of charge carriers confined in CuCl semiconductor nanocrystals (NCs) of different sizes (radius from 1.8 nm up to 28 nm) crystallized in a glass matrix are stud…
