title: Two-Dimensional, but not Flat: An All-Boron Graphene with a Corrugated Structure.
abstract: The construction of single-atom-thick sheets of boron on a silver substrate, which was published in late 2015, represents a significant advance towards the realization of useful two-dimensional materials based solely on boron. This Highlight provides background information on the topic of boron allotropes and an outlook for further work in this area.
