Abstract

Highly oriented ZnO thin films were fabricated by dip-coating technique using zinc acetate 2-methoxyethanol 2-aminoethanol solution as starting materials, and effects of substrates on the film's orientation were investigated. Product films were obtained by prefiring at 300, 400, 500 and 550℃ for 10 min, followed by final heat-treatment at the same temperatures as prefiring for 1h. c-axis oriented films on glass substrates were prepared by heat treatment of prefiring films at 300-550℃, while films on alumina showed polycrystalline structure. Films with c-axis orientation exhibited lower specific resistivities than those of polycrystalline films with partial crack and pore.
