摘要：

The simple growth model of pure a-axis-oriented YBa2Cu3Ox 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 YBa2Cu3Ox. Based on this hypothesis, the pure a-axis-oriented thin films are successfully obtained on (100)-oriented Nd2CuO4 substrates of K2NiF4-type structure.
