Atomically thick two-dimensional (2D) semiconducting materials have attract broad interest because of their low-dimensional effect. Towards optoelectronic applications, 2D semiconducting materials with tunable band structures (such as tunable band gaps, conducting band and valence band positions) are favored. Alloying is a general approach to tune the band structures. Here, this review introduces the research progresses on 2D semiconductor alloys in recent years, including their thermodynamic stability, controlled preparation, structure characterization and property investigation. The transition- metal dichalcogenide monolayer alloys, mainly Mo, W metal elements and S, Se dichalcogenide elements is focused.

Key words: 2D semiconductor alloy, transition-metal dichalcogenide, band engineering, micro spectroscopy, nano device
