Abstract

Metal-induced solid-phase crystallization of amorphous TiO ₂ thin films was investigated by introducing metal contact layers such as Ni or Cu between the TiO ₂ film and substrate. The crystallization temperature of TiO ₂ was found to be lowered by 30 °C (from ∼250 to ∼220 °C) with the use of a Ni contact layer. Based on the fact that part of the Ni atoms diffused to the surface of the crystallized TiO ₂ film, we proposed a reaction-assisted crystallization model in which an intermediate complex containing Ti-O and Ni-O bonds decomposes to crystallize TiO ₂ at a relatively low temperature.
