In the present paper we report a comparative study of the structural, morphologic, and electric properties of Pb(Zr,Ti)O3 films, deposited by pulsed metal-organic chemical vapour deposition (MOCVD), on different (111)-oriented bottom-electrode stacks (SrRuO3/Pt, Pt, and Ir substrates). The Pb input ratio in the MOCVD chamber was systematically modified for each deposition run to obtain PZT films with various compositions within the Pb process window. Our results clearly demonstrate that only PZT films deposited on SrRuO3 show high quality and reproducible properties throughout the process window, i.e., high (111) texture, low roughness (<5 nm), high Pr (∼40 µC/cm2), low Vc (<1 V), as well as a relatively low leakage current (∼10-5 A/cm2 at 1.5 V). This study provides further evidence that SrRuO3/Pt substrates are good candidates for integration in next-generation high-density ferroelectric random access memories (FeRAM).
