We study interfacial water trapped between a sheet of graphene and muscovite (mica) surface using Raman spectroscopy ultra-high vacuum scanning tunneling microscopy (UHV-STM) at room temperature. are able to image the graphene-water interface with atomic resolution, revealing layered network underneath graphene. identify layer numbers carbon nanotube height reference. Under normal conditions, structures remain stable. However, greater electron energies, we locally manipulate STM tip.
