The growth and study of materials showing novel topological states of matter is one of the frontiers in condensed matter physics. Among this class of materials, the nitride antiperovskite Cu₃PdN has been proposed as a new three-dimensional Dirac semimetal. However, the experimental realization of Cu₃PdN and the consequent study of its electronic properties have been hindered due to the difficulty of synthesizing this material. In this study, we report fabrication and both structural and transport characterization of epitaxial Cu₃PdN thin films grown on (001)-oriented SrTiO₃ substrates by reactive magnetron sputtering and post-annealed in …
