Ferroelectric Effect in Thin-Film Strontium Titanate
We show that thin-film strontium titanate can exhibit a high gigahertz permittivity and ferroelectricity at cryogenic temperatures. The symmetry breaking due to ferroelectricity results in a Pockels coefficient that surpasses that of lithium niobate.
