摘要

We have investigated the hole transport in smectic mesophases by Monte Carlo simulation based on a two-dimensional hopping transport in Gaussian-distributed density of states and time-of-flight experiments. We found that their unique carrier transport properties such as non-Poole-Frenkel type of behavior i.e.,field-and-temperature independent mobility, is well explained by the two-dimensional disorder model with a small Gaussian width of 50-60 meV. Furthermore, we found the Pool-Frenkel type of behavior in a biphenyl derivatives and at a low temperature range below ambient temperature in a therthiphene derivative and determined the Gaussian width to be 100～120meV and 50 meV, respectively. We came to a conclusion that the charge carrier transport in smectic mesophases can be explained by a 2-demensional disorder model with a small Gaussian width of the density of states σ, where a value of σ/kT plays important role to determine its behavior at a given temperature.
