Bismuth stm
WebPart B is devoted to STM (scanning tunneling microscopy) and STS (scanning tunneling spectroscopy) measurements which allow access to the atomic structure and to the electronic density of states. Sections B1 and B2 focus on STM/STS measurements on graphene supported on standard SiO 2 and on metallic substrates.
