Spectrally-resolved hyperfine interactions between polaron and nuclear spins in organic light emitting diodes: Magneto-EL studies
S. A. Crooker, F. Liu, M. R. Kelley +7
We use spectrally-resolved magneto-electroluminescence (EL) measurements to study the energy dependence of hyperfine interactions between polaron and nuclear spins in organic LEDs.…
Spin and Valley Noise in Two-Dimensional Dirac Materials
Wang-Kong Tse, A. Saxena, D. L. Smith +1
We develop a theory for optical Faraday rotation noise in two-dimensional Dirac materials. In contrast to spin noise in conventional semiconductors, we find that the Faraday rotati…
Role of Nuclear Quadrupole Coupling on Decoherence and Relaxation of Central Spins in Quantum Dots
N. A. Sinitsyn, Yan Li, S. A. Crooker +2
Strain-induced gradients of local electric fields in semiconductor quantum dots can couple to the quadrupole moments of nuclear spins. We develop a theory describing the influence…
"Listening" to the spin noise of conduction electrons in bulk n:GaAs
S. A. Crooker, L. Cheng, D. L. Smith
We report a comprehensive study of stochastic electron spin fluctuations -- spin noise -- in lightly doped (-type) bulk GaAs, which are measured using sensitive optical magnetom…
Morphology Effectively Controls Singlet-Triplet Exciton Relaxation and Charge Transport in Organic Semiconductors
V. K. Thorsmølle, R. D. Averitt, J. Demsar +7
We present a comparative study of ultrafast photo-conversion dynamics in tetracene (Tc) and pentacene (Pc) single crystals and Pc films using optical pump-probe spectroscopy. Photo…
Effects of strain, electric, and magnetic fields on lateral electron spin transport in semiconductor epilayers
M. Hruska, S. Kos, S. A. Crooker +2
We construct a spin-drift-diffusion model to describe spin-polarized electron transport in zincblende semiconductors in the presence of magnetic fields, electric fields, and off-di…
