  You can use SrTiO3 as a substrate. You can etch the substrate with buffered HF and anneal it in O2 to get a smooth surface. And you can use PBCO as buffered layer. It will be very hard to etch YBCO after your growth since YBCO is very sensitive and react with most of the chemical even water and air.

  It is not very important for SSPD if you can produce ultra-thin superconductor films with high quality according to my experience. But it is a big risk with the stability of YBCO film for fabricating such devices. I think.

  As per my knowledge SrTiO3 is suitable for your requirement.since it has less lattice miss match compare to that of LaAlO3 and YSZ substrates.

  For the purpose of particle detection I guess with either LaAlO3 or SrTiO3 you can get good enough films. For fine patterns I would advice photolitography.

  Thanks to you all.. I wonder, if it is any pre-deposition cleaning process for PLD? Did anybody has analysied before with different substrate with YBCO thin film for its physical & surface properties?
