Theory
of charge transport in organic diodes
and LEDs
Organic conjugated polymers are
a novel class of electronic materials
with many desireable and chemically
tunable mechanical and electronic
properties. Our work in this area
explores the fundimental photophysical
process in these systems following
electro- or photo-injection of an
electron/hole pair. We are interested
in the roles of electron/hole correlation,
polymer morphology, inter- and intra-chain
coupling, and vibrational dynamics
and how each of these effect device
performance.
Semi-classical methods for quantum
dynamics
Our work here is to develop new
theoretical tools based upon hydrodynamic
and semi-classical formulations
of quantum mechanics to study correlated
electronic transport in condensed
phase systems.
