Solution-processible high-permittivity nanocomposite gate insulators for organic field-effect transistors
(Georgia Institute of Technology, 2008-07-07)
We report on solution-processible high permittivity nanocomposite gate insulators based on BaTiO₃ nanoparticles, surface-modified with a phosphonic acid, in poly(4-vinylphenol) for organic field-effect transistors. The use ...
Experimental and theoretical study of temperature dependent exciton delocalization and relaxation in anthracene thin films
(Georgia Institute of Technology, 2008-02)
The spectroscopy of solid anthracene is examined both experimentally and theoretically. To avoid experimental complications such as self-absorption and polariton effects, ultrathin polycrystalline films deposited on ...
Highly efficient green phosphorescent organic light-emitting diodes with simplified device geometry
(Georgia Institute of Technology, 2008-06)
We report on the performance of green phosphorescent organic light-emitting diodes based on the well-known host 4,4′-di(carbazol-9-yl)-biphenyl and the green phosphor emitter fac tris(2-phenylpyridinato-N,C²′) iridium. ...
Simulations of the emission spectra of fac-tris(2-phenylpyridine) iridium and Duschinsky rotation effects using the Herman-Kluk semiclassical initial value representation method
(Georgia Institute of Technology, 2008-12-07)
The phosphorescent emission spectra of fac-tris(2-phenylpyridine) iridium [fac-Ir(ppy)₃] due to the lowest triplet T1 and T2 states are simulated using the harmonic oscillator approximation for the S0, T₁, and T₂potential ...
Improvement of the coupled-cluster singles and doubles method via scaling same- and opposite-spin components of the double excitation correlation energy
(Georgia Institute of Technology, 2008-03-28)
There has been much interest in cost-free improvements to second-order Moller-Plesset perturbation theory (MP2) via scaling the same- and opposite-spin components of the correlation energy (spin-component scaled MP2). By ...
