Electric Transport Properties and It's Anisotropy in Discotic Liquid Crystal

Abstract

Carrier generation and transport properties in a discotic liquid crystal have been studed using a time-of Hight Icchnique. By using two types of electrode configurations, taht is, a sapdwich and interdigitated clectrodes, the anisotoropy of the carrier mobility and dark conductivily has also been estimated. The carrier mobility in the directron perpendicular to the columnar axis in the discotic phase has been estimated to be smaller than that parallel to the columnar axis. The anisotropy in the dark conductivity is also confirmed in the discotic phase.
