Journal ArticleDOI
Mechanical Control of Spin States in Spin-1 Molecules and the Underscreened Kondo Effect
J. J. Parks,A. R. Champagne,T. A. Costi,William W. Shum,Abhay Pasupathy,Eric Neuscamman,Samuel Flores-Torres,Pablo S. Cornaglia,A. A. Aligia,C. A. Balseiro,Garnet Kin-Lic Chan,Héctor D. Abruña,Daniel C. Ralph +12 more
TL;DR: These findings demonstrate a mechanism of spin control in single-molecule devices and establish that they can serve as model systems for making precision tests of correlated-electron theories.
Journal ArticleDOI
Tuning the Kondo effect with a mechanically controllable break junction.
J. J. Parks,A. R. Champagne,Geoffrey R. Hutchison,Samuel Flores-Torres,Héctor D. Abruña,Daniel C. Ralph +5 more
TL;DR: The linear conductance as a function of T/T(K) agrees with the scaling function expected for the spin-1/2 Kondo problem and is able to tune finite-bias Kondo features which appear at the energy of the first C(60) intracage vibrational mode.
Journal ArticleDOI
Electrospun Light-Emitting Nanofibers
Jose M. Moran-Mirabal,Jason D. Slinker,John A. DeFranco,Scott S. Verbridge,Rob Ilic,Samuel Flores-Torres,Héctor D. Abruña,George G. Malliaras,Harold G. Craighead +8 more
TL;DR: Electrospun light-emitting nanofibers from ruthenium(II) tris(bipyridine)/polyethylene oxide mixtures, deposited on gold interdigitated electrodes and lit in a nitrogen atmosphere show light emission at low operating voltages, with turn-on voltages approaching the band gap limit of the organic semiconductor.
Journal ArticleDOI
Identification of a quenching species in ruthenium tris-bipyridine electroluminescent devices.
Leonard J. Soltzberg,Jason D. Slinker,Samuel Flores-Torres,Daniel A. Bernards,George G. Malliaras,Héctor D. Abruña,Ji-Seon Kim,Richard H. Friend,Michael D. Kaplan,Velda Goldberg +9 more
TL;DR: This work is the first to detect a specific chemical degradation product formed during iTMC OLED operation and identify this performance-degrading product to be the oxo-bridged dimer.
Journal ArticleDOI
Addition of a Phosphorescent Dopant in Electroluminescent Devices from Ionic Transition Metal Complexes
Ahmad R. Hosseini,Cheong Yang Koh,Jason D. Slinker,Samuel Flores-Torres,and Héctor D. Abruña,George G. Malliaras +5 more
TL;DR: In this article, the authors demonstrate tuning of the emission of ionic transition metal complexes in the red part of the spectrum by dispersing an ionic osmium complex into a ruthenium complex matrix, which leads to devices that are more efficient than those from pristine films of the matrix or the dopant alone.
