Among the family of elemental 2D materials, antimonene is predicted to have a desirable combination of bandgap tunability and exceptional physical properties. However, there is a lack of a facile synthesis technique to prepare high‐quality antimonene with large aspect ratios on standard SiO2 substrates, hindering wide scale exploration of this material. Here, a physical vapor deposition process to controllably achieve millimeter‐scale, β‐phase, monocrystalline antimonene nanosheets on a SiO2 dielectric substrate is reported. The temperature gradient across the deposition tube is exploited to realize either large‐area nanosheets or single antimonene crystals on‐demand. The composition and qua..View full abstract
