Abstract(in English) | We focus on realizing a high quality Bi_2Sr_2CaCu_2O_<8+x>(Bi-2212) thin film fabricated on an MgO substrate in order to apply the film to high frequency devices such as a terahertz oscillator and filter. In this study, SrTiO_3(STO) thin films which can be expected as a buffer layer and Bi-2212 thin films were fabricated on MgO substrates by the metal-organic decomposition(MOD) method which has the advantages such as its low running cost and ability to fabricate large-area films. By introducing the 2-step heat treatment and optimizing the temperature of precursor fabrication, we obtained the FWHM of 1.80° and 2.65° for the X-ray rocking curve and in-plane rocking curve of STO thin films, respectively. Further, we obtained the critical temperature(T_C) of about 75 K for Bi-2212 thin films by improving the heat treatment process. |
