摘要

A new topological crystalline insulator material, SnSe in the rock-salt structure, is obtained using molecular beam epitaxy. The thermodynamically unstable rock-salt SnSe phase is stabilized in epitaxial films up to 20 nm by a Bi₂Se₃ substrate. Dirac surface states are observed at both the Γ¯ and the M¯ points using angle-resolved photoemission spectroscopy; this confirms the topological crystalline insulator phase of the films.
