Spin relaxation dynamics of radical-pair processes at low magnetic fields
T. H. Tennahewa, S. Hosseinzadeh, S. I. Atwood +4
We report measurements of room-temperature spin-relaxation times and of charge-carrier spins in a -conjugated polymer thin film under bipolar injection and low ($1\m…
Spin-transport in an organic semiconductor without free charge carrier involvement
H. Popli, J. Wang, X. Liu +5
We have experimentally tested the hypothesis of free charge carrier mediated spin-transport in the small molecule organic semiconductor Alq3 at room temperature. A spin current was…
Floquet spin states in OLEDs
S. Jamali, V. V. Mkhitaryan, H. Malissa +11
Weakly spin-orbit coupled electron and hole spins in organic light-emitting diodes (OLEDs) constitute near-perfect two-level systems to explore the interaction of light and matter…
Spin-Dependent Charge-Carrier Recombination Processes in Tris(8-Hydroxyquinolinato) Aluminum
H. Popli, X. Liu, T. H. Tennahewa +5
We have studied the nature and dynamics of spin-dependent charge carrier recombination in Tris(8-hydroxyquinolinato) aluminum (Alq) films in light emitting diodes at room tempe…
Electric-field quenching of optically detected magnetic resonance in a -conjugated polymer
D. L. Baird, A. Nahlawi, K. Crossley +8
Electric fields are central to the operation of optoelectronic devices based on conjugated polymers since they drive the recombination of electrons and holes to excitons in organic…
High-Field Magnetoresistance of Organic Semiconductors
G. Joshi, M. Y. Teferi, S. Jamali +7
The magneto-electronic field effects in organic semiconductors at high magnetic fields are described by field-dependent mixing between singlet and triplet states of weakly bound ch…
