Abstract

We demonstrated that ultraviolet Raman spectroscopy is an effective technique to measure the transition temperature (T_c) in ferroelectric ultrathin films and superlattices. We showed that one-unit-cell-thick BaTiO₃ layers in BaTiO₃/SrTiO₃ superlattices are not only ferroelectric (with T_c as high as 250 kelvin) but also polarize the quantum paraelectric SrTiO₃ layers adjacent to them. T_c was tuned by ∼500 kelvin by varying the thicknesses of the BaTiO₃ and SrTiO₃ layers, revealing the essential roles of electrical and mechanical boundary conditions for nanoscale ferroelectricity.
