Title: Synthesis of the ferroelectric solid solution, Pb(Zr{sub 1-x}Ti{sub x})O{sub 3} on a single substrate using a modified molecular beam epitaxy technique

Abstract

High-throughput synthesis of the ferroelectric solid solution Pb(Zr{sub 1-x}Ti{sub x})O{sub 3} (PZT) on single Pt/Ti/SiO{sub 2}/Si substrates was demonstrated using a modified molecular beam epitaxy (MBE) system. The PZT films exhibited a phase transition from rhombohehdral to tetragonal symmetry as a function of Zr:Ti ratio, across the substrate diagonal. This was consistent with the presence of a morphotropic phase boundary at Zr:Ti ratio of 0.64:0.36, different from the value of 0.53:0.47 observed for bulk ceramics. All points on the films exhibited ferroelectric hysteresis. Results demonstrate the feasibility of high-throughput MBE for deposition of complex ferroelectric oxides, and pave the way for further materials discovery.
