The investigation of two-dimensional (2D) materials has developed rapidly in recent years, inspired by their unique properties and the promise of applications. Recently, many theoretical papers have reported a honeycomb lattice of antimony atoms with expected applications in electric and photoelectric devices [2], called antimonene[1].Here we report the growth of a monolayer of antimonene on layered PdTe2 substrates by epitaxy[3]. Combining our experimental and theoretical results, we verifed that the antimonene is a 2D continuous monolayer with weak coupling to the substrate. Moreover, our fndings reveal that the antimonene is quite inert with respect to air. The monolayer antimonene with its large bandgap and chemical stability is promising for applications in nanoelectronic devices.
