Emergent and Tunable Topological Surface States in Complementary Sb/Bi 2 Te 3 and Bi 2 Te 3 /Sb Thin-Film Heterostructures

Epitaxial thin-film heterostructures offer a versatile platform for realizing topological surface states (TSSs) that may be emergent and/or tunable by tailoring the atomic layering in the heterostructures. Here, as an experimental demonstration, Sb and Bi Te thin films with closely matched in-plane...
