High electrical conductivity in the epitaxial polar metals LaAuGe and LaPtSb
High electrical conductivity in the epitaxial polar metals LaAuGe and LaPtSb
Polar metals are an intriguing class of materials that simultaneously host free carriers and polar structural distortions. Despite the name "polar metal," however, most well-studied polar metals are poor electrical conductors. Here, we demonstrate the molecular beam epitaxial (MBE) growth of LaPtSb and LaAuGe, two polar metal compounds whose electrical …
