Quantum interference in second-harmonic generation from monolayer WSe2
Kai-Qiang Lin, Sebastian Bange, John M. Lupton
A hallmark of wave-matter duality is the emergence of quantum-interference phenomena when an electronic transition follows different trajectories. Such interference results in asym…
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…
Tuning effective hyperfine fields in PEDOT:PSS thin films by doping
M. Y. Teferi, J. Ogle, G. Joshi +6
Using electrically detected magnetic resonance spectroscopy, we demonstrate that doping the conducting polymer poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS)…
Revealing weak spin-orbit coupling effects on charge carriers in a -conjugated polymer
H. Malissa, R. Miller, D. L. Baird +7
We measure electrically detected magnetic resonance (EDMR) on organic light-emitting diodes (OLEDs) made of the polymer poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (M…
Light emission from gold nanoparticles under ultrafast near-infrared excitation: thermal emission, inelastic light scattering or multiphoton luminescence?
Lukas Roloff, Philippe Klemm, Imke Gronwald +3
Gold nanoparticles emit broad-band upconverted luminescence upon irradiation with pulsed infrared laser radiation. Although the phenomenon is widely observed, considerable disagree…
Determining the True Optical Gap in a High-Performance Organic Photovoltaic Polymer Using Single-Molecule Spectroscopy
Gordon J. Hedley, Florian Steiner, Jan Vogelsang +1
Low-gap conjugated polymers have enabled an impressive increase in the efficiencies of organic solar cells, primarily due to their red absorption which allows harvesting of that pa…
Role of Triplet-State Shelving in Organic Photovoltaics: Single-Chain Aggregates of Poly(3-hexylthiophene) versus Mesoscopic Multichain Aggregates
Florian Steiner, John M. Lupton, Jan Vogelsang
Triplet excitons have been the focus of considerable attention with regards to the functioning of polymer solar cells, because these species are long-lived and quench subsequently…
