Cascade spin dynamics of excitons localized in indirect-band-gap (In,Al)As/AlAs quantum dots with type-I band alignment
S. V. Nekrasov, I. V. Kalitukha, A. A. Golovatenko +5
We investigate the spin dynamics of excitons localized in type I (In,Al)As/AlAs quantum dots with an indirect in momentum space band structure. Polarized selective photoluminescenc…
Hyperfine versus exchange interaction in the spin dynamics of spatially indirect excitons in CsPbI perovskite nanocrystals
Timur S. Shamirzaev, Nataliia E. Kopteva, Dmitry S. Smirnov +7
We study the dynamics of recombination, optical orientation, and optical alignment of excitons in ensembles of CsPbI nanocrystals (NCs), synthesized in a glass matrix. In lar…
Fus3D: Decoding Consolidated 3D Geometry from Feed-forward Geometry Transformer Latents
Laura Fink, Linus Franke, George Kopanas +2
We propose a feed-forward method for dense Signed Distance Field (SDF) regression from unstructured image collections in less than three seconds, without camera calibration or post…
Magnetic field induced exciton spin dynamics in indirect band gap (In,Al)As/AlAs quantum dots
T. S. Shamirzaev, D. R. Yakovlev, D. S. Smirnov +5
The exciton recombination and spin dynamics are investigated both experimentally and theoretically in an ensemble of indirect band gap (In,Al)As/AlAs quantum dots (QDs) with type-I…
Influence of Gamma-X mixing on optical orientation and alignment of excitons in (In,Al)As/AlAs quantum dots
S. V. Nekrasov, N. O. Mikhailenko, M. D. Ragoza +2
The effect of Gamma-X mixing on the energy levels fine structure of indirect in k-space excitons in an ensemble of (In,Al)As/AlAs quantum dots with type I band alignment was experi…
Polarized photoluminescence and g-factor in an ensemble of quantum dots in magnetic fields
Lyubov Kotova, Timur Shamirzaev, Vladimir Kochereshko
In this paper, polarized photoluminescence caused by exciton quasi-equilibrium spin orientation on Zeeman sublevels in an ensemble of quantum dots of different sizes is theoretical…
