T. Matsui et al., CROSS-SECTIONAL OBSERVATION IN (103)-ORIENTED YBA2CU3OX SRTIO3/(013)-ORIENTED YBA2CU3OX TUNNEL JUNCTION/, JPN J A P 1, 34(1), 1995, pp. 111-112
Cross-sectional observation has been performed in a (103)-oriented YBa
2Cu3Ox(YBCO)/SrTiO3(STO)/(013)-oriented YBCO tunnel junction. Transmis
sion electron microscope (TEM) image revealed that dominant structures
of the top and bottom YBCO layers are formed by (100)-, (010)- and (0
01)-planes at the YBCO/STO interfaces and that amorphouslike layers ex
ist at both the top YBCO/STO and STO/bottom YBCO interfaces.
