| Abstract(in English) | Sapphire substrates are expected as suitable substrates of superconducting microwave devices, however, there are few reports on anisotropic dielectric constant of the sapphire substrates. Therefore, we examine the temperature dependence of dielectric constant. This paper presents the measured results of dielectric constants of r-, a-, and c-plane sapphire substrates by the cavity resonance method. Also, we have examined the conditions of epitaxial CeO_2 films on these sapphire substrates, and also examined epitaxial growth of YBa_2Cu_3O_<7-δ> films were grown on these CeO_2 buffer layers. |
