TL;DR: It is demonstrated that the HFI does indeed have a crucial role in all three spin responses and OLED films based on the D-polymers show substantially narrower magneto-electroluminescence and ODMR responses, and OSV devices based on D- polymers show a substantially larger magnetoresistance.

TL;DR: A giant Rashba splitting in this compound, with energy splitting of (40 ± 5) meV and Rashba parameter of (1.6 ± 0.1) eV·Å, is obtained, which shows that 2D hybrid perovskites have great promise for potential applications in spintronics.

TL;DR: In this paper, the authors apply low temperature confocal optical microscopy to spatially resolve, and spectroscopically study, a single self-assembled quantum dot and compare the emission spectra obtained at various excitation levels to a theoretical many body model, showing that radiative recombination is very weak and sharp spectral lines are due to optical transitions between confined multiexcitonic states among which excitons thermalize within their lifetimes.

TL;DR: The resonant Raman scattering (RRS) from the three modes of trans-polyacetylene and the charged-induced ir modes are analyzed with use of the amplitude- and phase-mode theories and it is shown that the observed phonon frequencies and the relative intensities of all modes obtained at various laser excitation energies are accounted for by a single phonon propagator.

TL;DR: A spin-OLED with ferromagnetic electrodes that acts as a bipolar organic spin valve (OSV) based on a deuterated derivative of poly(phenylene-vinylene) with small hyperfine interaction is designed, fabricated, and studied, which provides a pathway for organic displays controlled by external magnetic fields.
