Monoelemental 2D materials

In the last 15 years, the study of 2D materials such as graphene, single and few layers of transition metal dichalcogenides, and other materials in the form of sheets with a thickness on the atomic scale, has grown into a rapidly moving field. 2D materials are being explored for their intriguing fundamental properties and a wide range of applications in electronics, sensing, energy storage and harvesting, to name a few.

This web-collection highlights and brings together a curated selection of most recent papers published in Nature journals exploring basic physical properties and application of so-called monoelemental 2D materials. This branch of the 2D material family tree is composed of materials formed by a single chemical element. Conceptually most similar to graphene, this growing family includes remarkable materials such as 2D forms of Si, Ge, Sn, P, Te, Bi, B, etc. referred to as silicene, germanene, stanene, phosphorene, tellurene, bismuthine or borophene. Most of these materials have semiconducting band gaps and high mobilities making them interesting for applications in electronics and optoelectronics. Just like in the case of other 2D materials, their properties can be easily tuned by chemical and electrostatic doping or strain.


Group III (Borophene)

Group IV (Stanene)

Group-V (Bismuthene and Phosphorene)

Group VI (Tellurene)
