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…
A high precision falling-ball viscometer using a fast camera
Neal Samuel Border, Aiden Reilly, Addison Miller +2
This paper describes a simple and inexpensive method of measuring viscosity of a Newtonian fluid using the ball drop technique and an inexpensive point and shoot ~1000 frame per se…
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…
Efect of magnetic Gd impurities on superconductivity in MoGe films with different thickness and morphology
Hyunjeong Kim, Anil Ghimire, Shirin Jamali +3
We studied the effect of magnetic doping with Gd atoms on the superconducting properties of amorphous Mo70Ge30 films. We observed that in uniform films deposited on amorphous Ge, t…
Superconductor Insulator Transition in Long MoGe Nanowires
Hyunjeong Kim, Shirin Jamali, A. Rogachev
Properties of one-dimensional superconducting wires depend on physical processes with different characteristic lengths. To identify the process dominant in the critical regime we h…
