Research Abstract

The electric field-induced orientation of rubrene single crystals was observed in a nonpolar solvent. Rubrene single microcrystals responded to an AC electric field beyond a crystal-size dependent threshold. The maximum dipole moment induced in the longitudinal axis (b-axis) of rubrene single crystals on a SiO_2/Si substrate was aligned almost parallel to the direction of the applied electric field. Field-effect transistors with these orientated crystals exhibited low variability of the carrier mobility of 0.03~0.07 cm^2/Vs. The orientation technique is expected to be applied to the fabrication of large-area single-crystal FETs.
