Abstract
An electronic device substrate structure including a substratea metal thin filmas a (111)-oriented film of a face-centered cubic structure or as a (0001)-oriented film of a hexagonal closest packed structure formed on the substrateand a wurtzite type thin filmas a (0001)-oriented film of a wurtzite crystal structure formed on the metal thin filmwherein: each of the two thin films is a polycrystalline film containing at least two kinds of crystal grains different in direction of crystal orientation in the plane; when the metal thin filmis a (111)-oriented film, <11-20> axes in the plane of the wurtzite type thin filmare parallel to <1-10> axes in the plane of the metal thin filmand when the metal thin filmis a (0001)-oriented film, <11-20> axes in the plane of the wurtzite type thin filmare parallel to <11-20> axes in the plane of the metal thin film
