From monolayer to thin films: engineered bandgap in CVD grown Bi 2 Se (3−x) Sx topological insulator alloys.
Using chemical vapor deposition (CVD), the scalable growth of topological insulator alloys Bi 2Se (3–x)Sx with composition-tunable bandgap and free from surface-state pinning was achieved. This research paves the way for the controlled growth of topological insulators, suitable for quantum optoelectronics and spintronics applications.
