Few-layer MoS2 Dendrites as a Highly Active Humidity Sensor

This study introduces an improved chemical vapor deposition method to grow dendritic MoS2 nanomaterials. The grown MoS2 crystals have a dendritic shape with fractal and schedulable patterns. These morphologies are mainly initiated from the growth of double defects, and are regulated by S: Mo vapor ratio by characterizing their atomic structure. This study enhances the understanding of the growth mechanism of twin-derived crystals, extends their application from nanomaterials to 2D crystals, and provides a powerful and controllable method for small transition metal sulfide TMDCs. Shape engineering methods in electrochemical applications have evolved.Graphical abstract
