We report on the use of bromine intercalation of graphite to perform in situ tuning of the Schottky barrier height (SBH) formed at many-layer-graphene (MLG) semiconductor interfaces. The intercalation of Br into MLG simultaneously increases interlayer separation between the graphene planes, while at the same time giving rise to an increase (decrease) in the free hole carrier density (Fermi ener...

Success in isolating a 2D graphene sheet from bulky graphite has triggered intensive studies of its physical properties as well as its application 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 re...

The effect of staging (n≤ 3) on the two-dimensional (2D) Fermi surface of PdAl 2 Cl 8 acceptor-type graphite intercalation compounds (GICs) has been investigated by the Shubnikov-de Haas effect. For the stage 1 and stage 2 compounds, one and two fundamental frequencies are observed, respectively. The measured angular variation of the fundamental frequencies confirms the 2D nature of the stage 1...

Boron/carbon/nitrogen (B/C/N) materials and boron/carbon (B/C) having graphite-like layered structures were synthesized by using a chemical vapor deposition (CVD) method. Calcium (Ca) was intercalated into the B/C reaction of Ca with host film to form an intercalation compound second stage structure as main product. also co-intercalated lithium (Li) B/C/N liquid-alloy method compound. These are...

Carbon takes its name from the latin word carbo meaning charcoal. This element is unique in that its unique electronic structure allows for hybridization to build up sp3, sp2, and sp networks and, hence, to form more known stable allotropes than any other element. The most common allotropic form of carbon is graphite which is an abundant natural mineral and together with diamond has been known ...
