关于Twisted Bilayer Graphene (TGB)的哈密顿量推导,可直接参看Bistritzer和MacDonald在PNAS上的原文。更详细的推导可以参照发表在Wiley Online Library上的Handbook of Graphene Set-Vol8-chapter6。(其第八卷第六章也即里斯本大学的G.Catarina的硕士毕业论文)。总得来说在写TGB的哈密顿量时,有两个关键的点,一是...

In the hetero-site nucleation process, the increase of both H2and CH4flow rates are important for seeding and growth of the second layer graphene. The ratio of bilayer graphene domains to all graphene domains (RBLG) as a function of the ratio of H2flow rate in step II to that in step ...

In the present work, we consider the excitonic effects in the twisted bilayer graphene (tBLG) within the rotated bilayer Hubbard model. Both, intralayer and interlayer Coulomb interactions have been considered and the half-filling condition is imposed for the electronic densities is both layers of...
When a single layer of graphene is stacked together to form bilayer graphene, just like vdWHs, especially when the lattice of the upper and lower layers is twisted, the superlattice is formed. The novel electronic...

Twisted bilayer graphene with a twist angle of around 1.1° features a pair of isolated flat electronic bands and forms a platform for investigating strongly correlated electrons. Here, we use scanning tunnelling microscopy to probe the local properties
