Bragg-enhanced time-domain Brillouin scattering from a propagating acoustic grating
O. S. Ken, D. O. Horiachyi, V. L. Korenev +4
Generation and detection of coherent phonons in semiconductors by femtosecond optical pulses is a powerful tool for high-frequency acoustic control of their electronic properties.…
Spin-dependent exciton-exciton interactions in a mixed lead halide perovskite crystal
Stefan Grisard, Artur V. Trifonov, Thilo Hahn +6
We investigate the two-pulse photon echo response of excitons in the mixed lead halide perovskite crystal \sample in dependence on the excitation intensity and polarization of the…
Giant optical orientation of exciton spins in lead halide perovskite crystals
Natalia E. Kopteva, Dmitri R. Yakovlev, Eyüp Yalcin +11
Optical orientation of carrier spins by circularly polarized light is the basis of spin physics in semiconductors. Here, we demonstrate strong optical orientation of 85\%, approach…
Long-lived exciton coherence in mixed-halide perovskite crystals
Stefan Grisard, Artur V. Trifonov, Ivan A. Solovev +5
Compositional engineering of the optical properties of hybrid organic-inorganic lead halide perovskites is one of the cornerstones for the realization of efficient solar cells and…
Trion magnetic polarons in (Cd,Mn)Te/(Cd,Mn,Mg)Te quantum wells
F. Godejohann, R. R. Akhmadullin, K. V. Kavokin +7
A trion magnetic polaron formed by the exchange interaction of a positively charged exciton (trion) with localized spins of Mn ions is found experimentally in a 4\,nm wide C…
Multiple Rabi rotations of trions in InGaAs quantum dots observed by photon echo spectroscopy with spatially shaped laser pulses
S. Grisard, H. Rose, A. V. Trifonov +9
We study Rabi rotations arising in intensity-dependent photon echoes from an ensemble of self-assembled InGaAs quantum dots. To achieve a uniform distribution of intensities within…
