WebMay 16, 2024 · 2.1 Monolayer Graphene. Graphene or monolayer graphene is a sheet of carbon atoms where a unit cell contains a pair of sublattices denoted by A and B. In the first Brillouin zone, we count six corners, which we arrange in two sets, K and K ’.The band structure of graphene is well described by the tight binding approximation including only …
WebNov 9, 2012 · 2. Band Structure. The starting point for understanding the electronic structure of bilayer and trilayer graphene is obtaining their band structure. The gap between the valence and conduction bands can be varied by external perpendicular electric field in BGs though it varies the overlap between the valence and conduction bands in TGs . WebTo understand the nature of these states, we first calculate the band structure of TLG using a continuum k ...
