Ca intercalated bilayer graphene as a thinnest limit of …

Success in isolating a 2D graphene sheet from bulky graphite has triggered intensive studies of its physical properties as well as its appliion in devices. Graphite intercalation compounds (GICs) have provided a platform of exotic quantum phenomena such as superconductivity, but it is unclear whether such intercalation is feasible in the thinnest 2D limit (i.e., bilayer graphene). Here we
