Hi! Here are some of the reference materials I have. Unfortunately I don't have too much about PZT because I'm working with AlN, but here it goes! A. L. Kholkin, "Piezoelectric properties of Ca-modified PbTiO3 thin films", Applied Physics Letters 69 (23) 2 December 1996. I. Kanno, "Piezoelectric properties of c-axis oriented Pb(Zr,Ti)O3 thin films", Appl. Phys. Lett. 70 (11), 17 March 1997 G. Yi, "Preparation of Pb(Zr,Ti)O3 thin films by sol gel processing", J. Appl. Phys. 64 (5), 1 September 1988 M. Toyama, "Characterization of piezoelectric properties of PZT thin films", Sensors and actuators A 45 (1994) 125-129 A good general paper is: D. Polla, "Processing and Characterization of Piezo Materials and integration into MEMS", Annu. Rev. Mater. Sci. 1998, 28:563-97 So what are you working on for your PhD? I'm trying to develop an AlN piezoelectric resonator, and aiming to have it operate at around 2 GHz. Karen Chow.
