摘要：
We report a simple, single-cycle synthetic method for forming highly-crystalline, micron-sized monolayer domains of phase-pure MoS2. This method combines liquid chemistry with discrete, layer-by-layer deposition from a novel Mo precursor. Single-crystalline MoS2 with domain sizes up to 100 mu m have been obtained and characterised by optical and electron microscopy as well as Raman and photoluminescence spectroscopy.
