Abstract
We have investigated temperature dependence of resistivity (ρ) and current-voltage characteristics of cobalt-phthalocyanine (CoPc) films deposited (i) along the 36.8° boundary (ATB) and (ii) in the single crystal region (SCR) of SrTiO3 bicrystal substrates. The analyses of ρ-T data show that while ATB films exhibit critical behavior, SCR films follow insulating three-dimensional variable-range-hopping mechanism. The mobility (μ) at 300 K has been estimated to be ∼148 and 3.8×10−3 cm2 V−1 s−1, respectively for ATB and SCR films. A very high μ for ATB films indicates that the bicrystal boundary acts as a template for the ordering of CoPc molecules.
