Abstract

Film studies: Epitaxial films of BaZrN2 (see TEM image) and BaHfN2 are grown by polymer-assisted deposition on SrTiO3 (STO) substrates. The films are phase-pure, allowing the intrinsic physical properties of the ternary nitrides to be studied. From 5 to 300 K, the films exhibit metallic-like resistivity–temperature behavior, with large residual resistivity ratios.
