Photocathodes that produce electron beams for electron
microscopes and advanced accelerators can be refreshed and rebuilt
repeatedly without opening the devices that rely on them, provided
the electron emitting materials are deposited on single-atom-thick
layers of carbon known as graphene, according to a new study
published in the journal Applied Physics Letters.
