Abstract

The simple growth model of pure a-axis-oriented YBa₂Cu ₃O_x thin films on (100)-oriented SrLaGaO₄ substrates of a K₂NiF₄-type structure is proposed. This is called "atomic graphoepitaxy". The model is based on an atomic-scale geometry of the (100) surface of K₂NiF₄-type substrates, which is characterized by atomic-scale grooves made of oxygen octahedra running along the 〈010〉 direction. These grooves are assumed to act as preferential nucleation sites of c-axis in-plane-aligned, a-axis-oriented YBa ₂Cu₃O_x. Based on this hypothesis, the pure a-axis-oriented thin films are successfully obtained on (100)-oriented Nd ₂CuO₄ substrates of K₂NiF₄-type structure.
