Abstract Unlike the unstable black phosphorous, another two-dimensional group-VA material, antimonene, was recently predicted to exhibit good stability and remarkable physical properties. However, synthesis of high-quality monolayer or few-layer antimonenes, sparsely reported, has greatly hindered development this new field.
