Excitons in two coupled conjugated polymer chains
Z. G. Yu, M. W. Wu, X. S. Rao +2
We have studied the exciton states in two coupled conjugated polymer chains which are modeled individually by the Su-Schrieffer-Heeger Hamiltonian and coupled by an interchain elec…
Theory of photoinduced charge transfer in weakly coupled donor-acceptor conjugated polymers: application to an MEH-PPV:CN-PPV pair
M. W. Wu, E. M. Conwell
In a pair of coupled donor-acceptor conjugated polymer chains, it is possible for an exciton photoexcited on either polymer to decay into a hole in the donor polymer's valence band…
Effect of interchain coupling on conducting polymer luminescence: excimers in derivatives of poly(phenylene vinylene)
M. W. Wu, E. M. Conwell
Optical excitation of a chain in a polymer film may result in formation of an excimer, a superposition of on-chain excitons and charge-transfer excitons on the originally excited c…
Contact Injection into Polymer Light-Emitting Diodes
E. M. Conwell, M. W. Wu
The variation of current I with voltage V for poly(phenylene vinylene) and other polymer light-emitting diodes has been attributed to carriers tunneling into broad conduction and v…
Transport in -Sexithiophene Films
M. W. Wu, E. M. Conwell
The field-effect mobility of hole polarons in -sexithiophene, measured in thin film transistors, was shown to be well fitted by Holstein's small polaron theory. Unfortunately, H…
