The discovery of graphene, a material made of one or very few atomic layers of carbon, started a boom. Today, such two-dimensional materials are no longer limited to carbon and are hot prospects for many applications, especially in microelectronics. In the journal Angewandte Chemie, scientists have now introduced a new 2-D material: they successfully modified arsenene (arsenic in a graphene-like structure) with chloromethylene groups.
Two-dimensional materials are crystalline materials made of just a single or very few layers of atoms that often display unusual properties. However, the use of graphene for applications such as transistors is limited because it behaves more like a conductor than a semiconductor. Modified graphene and 2-D materials based on other chemical elements with semiconducting properties have now been developed. One such material is β-arsenene, a two-dimensional arsenic in a buckled honeycomb structure derived from gray arsenic. Researchers hope that modification of this previously seldom-studied material could improve its semiconducting properties and lead the way to new applications in fields such as sensing, catalysis, optoelectronics, and other semiconductor technologies.
