Optical readout of singlet fission biexcitons with photoluminescence detected magnetic resonance
Gajadhar Joshi, Ryan D. Dill, Karl J. Thorley +3
Molecular spin systems based on photoexcited triplet pairs formed via singlet fission (SF) are attractive as carriers of quantum information because of their potentially pure and c…
Perdeuteration of poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (d-MEHPPV): control of microscopic charge-carrier spin-spin coupling and of magnetic-field effects in optoelectronic devices
Dani M. Stoltzfus, Gajadhar Joshi, Henna Popli +14
Control of the effective local hyperfine fields in a conjugated polymer, poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV), by isotopic engineering is reported. T…
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…
Morphology effects on spin-dependent transport and recombination in polyfluorene thin films
Richards Miller, K. J. van Schooten, H. Malissa +4
We have studied the role of spin-dependent processes on conductivity in polyfluorene (PFO) thin films by conducting continuous wave (c.w.) electrically detected magnetic resonance…
Separating hyperfine from spin-orbit interactions in organic semiconductors by multi-octave magnetic resonance using coplanar waveguide microresonators
Gajadhar Joshi, Richards Miller, Lillie Ogden +8
Separating the influence of hyperfine from spin-orbit interactions in spin-dependent carrier recombination and dissociation processes necessitates magnetic resonance spectroscopy o…
