Previous studies have shown the importance of unidirectionally aligned domain nucleation for the growth of 2D semiconductor single crystals. Here, the authors report the observation of a self-alignment process of misoriented domains during the metal-organic chemical vapour deposition growth of 2D MoS2 on sapphire, leading to single-crystalline films with improved carrier mobility.
