In our previous study, we reported nonmetal-metal transition in Li-incorporated Cu₃N polycrystalline films. Currently, we examine the relationship between Li-incorporation behavior and the orientation of Cu₃N films. We revealed that the concentration of incorporated Li in Cu₃N epitaxial films was much larger than that in polycrystalline ones. As a result, electronic properties of epitaxial films and polycrystalline ones were found to be substantially different. In this presentation, we present the orientation dependent Li-incorporation and the difference in the electronic properties.
