Theoretical characterization of titanyl phthalocyanine as a p-type organic semiconductor: Short intermolecular π-π interactions yield large electronic couplings and hole transport bandwidths
(Georgia Institute of Technology, 2008-01-21)
The charge-transport properties of the triclinic phase II crystal of titanyl phthalocyanine (α-TiOPc) are explored within both a hopping and bandlike regime. Electronic coupling elements in convex- and concave-type dimers ...
Optimizing organic photovoltaics using tailored heterojunctions: A photoinduced absorption study of oligothiophenes with low band gaps
(Georgia Institute of Technology, 2008-02)
A power conversion efficiency of 3.4% with an open-circuit voltage of 1 V was recently demonstrated in a thin film solar cell utilizing fullerene C60 as acceptor and a new acceptor-substituted oligothiophene with an optical ...
Electronic and vibronic interactions at weakly bound organic interfaces: The case of pentacene on graphite
(Georgia Institute of Technology, 2008-07)
The electronic and vibronic processes at the interface between a pentacene monolayer and a graphite surface were characterized using a combination of density-functional theory (DFT) and dynamic vibronic coupling simulations. ...
A theoretical view on self-assembled monolayers in organic electronic devices
(Georgia Institute of Technology, 2008-04)
Self-assembled monolayers (SAMs) of covalently bound organic molecules are rapidly becoming an integral part of organic electronic devices. There, SAMs are employed to tune the work function of the inorganic electrodes in ...
