It is known that transition metal chalcogenides take various structural polymorphisms depending on the combination of transition metals and chalcogens. Among them, the 3R structure has a characteristic structure in which both in-plane symmetry and out-of-plane symmetry are broken. In this presentation, we report on the unique superconducting properties of the polar superconductor 3R-TaSe2 produced by the molecular beam epitaxy method.
