When a crystal is subjected to a periodic potential, under certain circumstances it can adjust
itself to follow the periodicity of the potential, resulting in a commensurate state. Of particular …

Bilayer graphene has been a subject of intense study in recent years. The interlayer registry
between the layers can have dramatic effects on the electronic properties: for example, in …

In this article, we derive an effective theory of graphene on a hexagonal boron nitride (h-BN)
substrate. We show that the h-BN substrate generically opens a spectral gap in graphene …

Graphene has demonstrated great promise for future electronics technology as well as
fundamental physics applications because of its linear energy–momentum dispersion …

The crystal structure of a material plays an important role in determining its electronic
properties. Changing from one crystal structure to another involves a phase transition that is …

Graphene nanoribbons (GNRs) possess distinct symmetry-protected topological phases. We
show, through first-principles calculations, that by applying an experimentally accessible …

Graphene/hexagonal boron nitride (h-BN) has emerged as a model van der Waals
heterostructure as the superlattice potential, which is induced by lattice mismatch and crystal …

When two identical two-dimensional periodic structures are superposed, a mismatch rotation
angle between the structures generates a superlattice. This effect is commonly observed in …

The interaction between a graphene layer and a hexagonal boron nitride (hBN) substrate
induces lateral displacements and strains in the graphene layer. The displacements lead to …

Two-dimensional atomic crystals can radically change their properties in response to
external influences, such as substrate orientation or strain, forming materials with novel …
