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…

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…
