Semiconductors: Growth of Large-Area 2D MoS2(1-x ) Se2x Semiconductor Alloys (Adv. Mater. 17/2014)

Alloying in monolayers enables bandgap tuning in twodimensions. On page 2648, L. Xie, J. Zhang, and co-workers demonstrate that by direct evaporation of two end materials (MoS2 and MoSe2) and deposition at low temperatures, large-area 2D MoS2(1−x)Se2x monolayers are obtained. By changing the S/Se composition, the bandgap of MoS2(1−x)Se2x monolayers can be continuously tuned.
