Energy-gap Opening and Quenching in Graphene under Periodic External Potentials
Aihua Zhang, Zhenxiang Dai, Lei Shi +2
In this paper, we investigated the effects of periodic external potentials on properties of charge carriers in graphene using both the first-principles method based on density func…
Band gap engineering in graphene and hexagonal BN antidot lattices: A first principles study
Aihua Zhang, Hao Fatt Teoh, Zhenxiang Dai +2
Effects of antidot lattices on electronic structures of graphene and hexagonal BN (h-BN) are investigated using the first principles method based on density functional theory. For…
Massless Dirac Fermions in Graphene under an External Periodic Magnetic Field
Shuanglong Liu, Argo Nurbawono, Na Guo +1
By solving two-component spinor equation for massless Dirac Fermions, we show that graphene under a periodic external magnetic field exhibits a unique energy spectrum: At low energ…
Reversible magnetism switching in graphene-based systems via the decoration of photochromic molecules
Argo Nurbawono, Chun Zhang
By first principles calculations, we demonstrate that when decorated with photochromic molecules, it is possible to use light to reversibly control the magnetic properties of a nan…
Electronic and Transport Properties of Molecular Junctions under a Finite Bias: A Dual Mean Field Approach
Shuanglong Liu, Yuan Ping Feng, Chun Zhang
We show that when a molecular junction is under an external bias, its properties can not be uniquely determined by the total electron density in the same manner as the density func…
