摘要

Abstract: Inverted cylindrical magnetron sputtering (ICM) is areliable and reproducible method for the production ofHTSC thin films. This allows systematic studies of filmgrowth as a function of various deposition parametersincluding film thickness, substrate material, or bufferlayers. We report the growth conditions and growthquality of 1-2-3 films of different orientation withspecial emphasis on a-axis films which may be ofinterest for applications if 3-dimensional patterningis attempted. Substrate orientation and substratetemperature are the essential parameters controllingthe growth orientation. High quality buffer layers(FWHM mosaic spread $LS 0.2$DGR@, X$-min$/ $LS 5% inchanneling experiment) of Zr(Y)O$-2$/ could bedeposited on R- plane sapphire. Critical currentdensities near 3 $MUL 10$+6$/ A/cm$+2$/ at 77 K couldbe achieved for the 1-2-3 films deposited on thesebuffer layers. Finally we report results of in situBiSrCaCuO thin film deposition revealing first signs ofchanneling behavior (X$-min$/ $APEQ 60%) indicatingtoward epitaxial growth.!3
