Scientists are in the constant search of novel materials, or innovative applications of existing materials to solve problems we face in our everyday life. Although graphene, the two-dimensional (2D) form of carbon, has been a star player for the past decade, there is a significant shift towards other noncarbon materials in recent years. Apart from the large family of transition metal dichalcogenides (TMDs), mono-elemental materials, such as phosphorene, arsenene, antimonene, and silicene, are rapidly gaining attention. Composites and heterogenous layered structures are also worthy of interest.
