Query: Electronic transport within a quasi two-dimensional model for rubrene
  single-crystal field effect transistors   Spectral and transport properties of the quasi two-dimensional adiabatic
Su-Schrieffer-Heeger model are studied adjusting the parameters in order to
model rubrene single-crystal field effect transistors with small but finite
density of injected charge carriers. We show that, with increasing temperature
$T$, the chemical potential moves into the tail of the density of states
corresponding to localized states, but this is not enough to drive the system
into an insulating state. The mobility along different crystallographic
directions is calculated including vertex corrections which give rise to a
transport lifetime one order of magnitude smaller than spectral lifetime of the
states involved in the transport mechanism. With increasing temperature, the
transport properties reach the Ioffe-Regel limit which is ascribed to less and
less appreciable contribution of itinerant states to the conduction process.
The model provides features of the mobility in close agreement with
experiments: right order of magnitude, scaling as a power law $T^{-\gamma}$,
with $\gamma$ close or larger than two, and correct anisotropy ratio between
different in-plane directions. Due to a realistic high dimensional model, the
results are not biased by uncontrolled approximations.
