We fabricate thin films of pentacene by coating flake crystals dispersed in a liquid media. The films are structured with oriented crystals and have a well-defined grain structure obtained from the source crystals. The films assembled with large or small crystals show the carrier mobility of 1 cm2/V s and above 0.01 cm2/V s, respectively. Small electrode contact resistance of the films and transport barrier heights below 56 meV were confirmed from the temperature dependence of the mobility.
