摘要：Monoelemental two-dimensional materials are well known as Xenes. The representatives graphene and phosphorene have received considerable attention because of their outstanding physical properties. In recent years, the family members of Xenes have greatly increased, and the emerging ones are gaining more and more interest. In this review, we mainly focus on the recently developed Xenes in groups IIIA, VA, and VI. Comprehensive discussions of the latest progress are given in the aspects of basic physical properties and intriguing applications in photonics, optoelectronics, energy, and biomedicines.
