Since the pioneering studies in 2004, graphene, an allotrope of carbon with atomically thin layers of sp2-hybridized atoms, has attracted considerable interest due to its fascinating and exotic properties. Motivated by the success of graphene, alternative emerging 2D members have become promising candidates for various applications. Here, we have investigated the phase evolution of three Zintl zinc antimonides. In particular, 2D ZnSb features the sp2 hybridization with weak van der Waals forces in the interlayer interactions. Captured by the aberration-corrected STEM study, the stacking configuration of constituent atoms implies its exfoliatable behavior. Meanwhile, 2D ZnSb achieves high room-temperature carrier mobility, comparable to those of other representative 2D materials. |
