Type: article
Abstract: An artificial grain boundary Josephson junction in a BiSrCaCuO thin film was fabricated on an off-oriented SrTiO3(110) substrate using a MgO buffer layer, and was investigated using a transmission electron microscope (TEM). The MgO buffer layer was oriented with a (110) plane parallel to the (110) plane of the 5° off-oriented SrTiO3 substrate. The BiSrCaCuO film was grown with the c-axis normal to the (110) plane of the MgO buffer layer, while it had an (11n) orientation on the SrTiO3(110) substrate. Consequently, an artificial grain boundary was formed in the BiSrCaCuO film at the edge of the MgO buffer layer, and it was clearly observed with cross-sectional TEM.
