The simple growth model of pure a-axis-oriented YBa2Cu 3Ox 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 2Cu3Ox. Based on this hypothesis, the pure a-axis-oriented thin films are successfully obtained on (100)-oriented Nd 2CuO4 substrates of K2NiF4-type structure.
