Carbon nanomembranes (CNMs), made by radiation-induced crosslinking of aromatic self-assembled monolayers, are described by A. Turchanin and A. Gölzhäuser on page 6075. The image shows a large-area CNM with a thickness of 1 nm, spanning a hexagonal metal grid. This is a microscopy image made by a novel imaging technique - helium-ion microscopy.
Keywords: 2D materials; carbon nanomembranes; graphene; molecular self-assembly; nanofabrication.
