Topological phases with insulating bulk and gapless surface or edge modes have attracted
intensive attention because of their fundamental physics implications and potential …

Due to the unique band structure, graphene exhibits a number of exotic electronic properties
that have not been observed in other materials. Among them, it has been demonstrated that …

Two two-dimensional carbon allotropes comprised of octagons and pentagons are
proposed based on the first-principles calculations. The two carbon allotropes, named OPG …

The electron transport of different conical valleys is investigated in graphene with extended
line defects. Intriguingly, the electron with a definite incident angle can be completely …

In addition to electron charge and spin, novel materials host another degree of freedom, the
valley. For a junction composed of valley filter sandwiched by two normal terminals, we …

Graphene supports long spin lifetimes and long diffusion lengths at room temperature,
making it highly promising for spintronics. However, making graphene magnetic remains a …

Using the tight-binding model and the nonequilibrium Green's function method, we study
Andreev reflection in a graphene-superconductor junction, where graphene has two …

Charge carrier transport in single-layer graphene with one-dimensional charged defects is
studied theoretically. Extended charged defects, considered an important factor for mobility …

We investigate electron-derived thermal transport in zigzag graphene nanoribbons (ZGNRs)
with topological line defects (TLDs) including tetragon-TLD (4-TLD), octagon-TLD (8-TLD) …

At the interface between two-dimensional materials with different topologies, topologically
protected one-dimensional states (also named zero-line modes) arise. Here, we focus on …
