Non-Bloch-Siegert-type power-induced shift of two-photon electron paramagnetic resonances of charge-carrier spin states in an OLED
S. I. Atwood, S. Hosseinzadeh, V. V. Mkhitaryan +7
We present Floquet theory-based predictions and electrically detected magnetic resonance (EDMR) experiments scrutinizing the nature of two-photon magnetic resonance shifts of charg…
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…
Comparative analysis of magnetic resonance in the polaron pair recombination and the triplet exciton-polaron quenching models
V. V. Mkhitaryan, D. Danilovic, C. Hippola +2
We present a comparative theoretical study of magnetic resonance within the polaron pair recombination (PPR) and the triplet exciton-polaron quenching (TPQ) models. Both models hav…
Polaron spin echo envelope modulations in an organic semiconducting polymer
V. V. Mkhitaryan, V. V. Dobrovitski
Theoretical treatment of the electron spin echo envelope modulation (ESEEM) spectra from polarons in a semiconducting - conjugated polymer is presented. The contact hyperfine co…
Quantum dynamics of nuclear spins and spin relaxation in organic semiconductors
V. V. Mkhitaryan, V. V. Dobrovitski
We investigate the role of the nuclear spin quantum dynamics in hyperfine-induced spin relaxation of hopping carriers in organic semiconductors. The fast hopping regime with a smal…
Hyperfine-induced spin relaxation of a diffusively moving carrier in low dimensions: implications for spin transport in organic semiconductors
V. V. Mkhitaryan, V. V. Dobrovitski
The hyperfine coupling between the spin of a charge carrier and the nuclear spin bath is a predominant channel for the carrier spin relaxation in many organic semiconductors. We th…
