Chemical instability at chalcogenide surfaces impacts chalcopyrite devices well beyond the surface

Anion vacancies are a hurdle for technologies based on chalcogenide semiconductors and topological insulators. Even at room temperature, oxidation and cyanide etching can lead to selenium vacancies in CuInSe2 photovoltaic material but suitable post deposition treatments can mitigate their effect.
