Abstract

The equilibrium orientation of Pt in contact with (100)-SrTiO₃, at 1050°C and in an Ar/2 % O₂ environment, was determined by solid-state dewetting of continuous Pt films on single crystal SrTiO₃ substrates. Given the similar lattice parameters between Pt and SrTiO ₃, a simple cube-on-cube orientation relationship was expected to form at equilibrium. However, only a preferred orientation of Pt {111} parallel to the SrTiO₃ (100) surface formed, without a low-index orientation relationship. It was found that reconstruction of the SrTiO₃ surface (a complexion) was responsible for the Pt particle texture. The equilibrium crystal shape of the Pt particles was analyzed and it was found to contain the following facets: {111}, {100}, {110}, and {113}.
