Ferroelectric thin film, electronic element using name, and method for manufacturing ferroelectric thin film

Abstract

It is an object to provide a ferroelectric thin film having much higher ferroelectric properties than conventional Sc-doped ferroelectric thin film constituted by aluminum nitride and also having stability when applied to practical use, and also to provide an electronic device using the same. There are provided a ferroelectric thin film represented by a chemical formula M11-XM2XN, wherein M1 is at least one element selected from Al and Ga, M2 is at least one element selected from Mg, Sc, Yb, and Nb, and X is within a range of 0 or more and 1 or less, and also an electronic device using the same.
