UnravelingSulfur Vacancy Evolution Mechanism duringLow-Temperature H2 and S Vapor Annealing in Monolayer Mo(1– x )W x S2 Alloys

Abstract This study systematically modulated the healing and creation of S vacancies in monolayer Mo(1–x)WxS2 alloys via low-temperature H2 and S vapor annealing, observing three distinct types of photoluminescence (PL) evolutions. Type I featured intensified PL, a decreased X–/X...
