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 ...
Integrated organic photovoltaic modules with a scalable voltage output
(Georgia Institute of Technology, 2006-12)
Efficient organic photovoltaic modules and cells have been fabricated based on a blend of poly(3-hexylthiophene) (P3HT) and a soluble C₇ ₀ derivative, [6,6]-phenyl C₇ ₁ butyric acid methyl ester (PCBM-70). Power conversion ...
Third-order optical autocorrelator for time-domain operation at telecommunication wavelengths
(Georgia Institute of Technology, 2004-07)
We report on amorphous organic thin films that exhibit efficient third-harmonic generation at telecommunication wavelengths. At 1550 nm, micrometer-thick samples generate up to 17 mW of green light with input power of 250 ...
Efficient thin-film organic solar cells based on pentacene/C-60 heterojunctions
(Georgia Institute of Technology, 2004-11)
We have fabricated an efficient organic photovoltaic cell based on a heterojunction of pentacene and C ₆₀. Photocurrent action spectra exhibit broad light-harvesting throughout the visible spectrum with a peak external ...
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. ...
