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…
Ultrafast dynamics of optically excited charge carriers in the room-temperature antiferromagnetic semiconductor -MnTe
Changqing Zhu, Patrick Pilch, Anneke Reinold +6
We report on time-resolved optical and terahertz ultrafast spectroscopy of charge-carrier dynamics in the room-temperature antiferromagnetic semiconductor -MnTe. By optically pu…
Spin-Flip Raman Scattering on Electrons and Holes in Two-Dimensional (PEA)PbI Perovskites
C. Harkort, D. Kudlacik, N. E. Kopteva +6
The class of Ruddlesden-Popper type (PEA)PbI perovskites comprises two-dimensional (2D) structures whose optical properties are determined by excitons with a large binding…
Weak dispersion of exciton Landé factor with band gap energy in lead halide perovskites: Approximate compensation of the electron and hole dependences
N. E. Kopteva, D. R. Yakovlev, E. Kirstein +11
The photovoltaic and optoelectronic properties of lead halide perovskite semiconductors are controlled by excitons, so that investigation of their fundamental properties is of crit…
Optical orientation of excitons in a longitudinal magnetic field in indirect band gap (In,Al)As/AlAs quantum dots with type-I band alignment
T. S. Shamirzaev, A. V. Shumilin, D. S. Smirnov +5
The exciton recombination and spin dynamics in (In,Al)As/AlAs quantum dots (QDs) with indirect band gap and type-I band alignment are studied. The negligible (less than eV)…
