Chemical Vapor Deposition of High‐Optical‐Quality Large‐Area Monolayer Janus Transition Metal Dichalcogenides (Adv. Mater. 38/2022)

Janus Monolayers In article number 2205226, Bernhard Urbaszek, Antony George, Andrey Turchanin, and co-workers present a new method to grow large-scale and high-structural-quality SeMoS Janus monolayers on Au substrates. Their high optical quality is demonstrated by optical and magneto-optical measurements which reveal the strong exciton-phonon coupling and enable an exciton g-factor of −3.3 to be obtained.
