Ground state determination and band gaps of bilayers of graphenylenes and octafunctionalized-biphenylenes
(2019-06-15)
Device fabrication often requires materials that are either reliably conducting, reliably semiconducting, or reliably nonconducting. Bilayer graphene (BLG) changes from a superconductor (Cao et al., 2018) to a semiconductor ...
Molecular Beam Epitaxy of GaN Nanowires on Epitaxial Graphene
(Amer Chemical Soc, 2017-09-01)
We demonstrate an all-epitaxial and scalable growth approach to fabricate single-crystalline GaN nanowires on,graphene by plasma-assisted molecular beam epitaxy. As substrate, we explore several types of epitaxial graphene ...
Quantum phase transitions into Kondo states in bilayer graphene
(American Physical Society, 2014-02)
We study a magnetic impurity intercalated in bilayer graphene. A representative configuration generates a hybridization function with strong dependence on the conduction-electron energy, including a full gap with one hard ...
One-way transport in laser-illuminated bilayer graphene: A Floquet isolator
(American Physical Society, 2017-12-08)
We explore the Floquet band structure and electronic transport in laser-illuminated bilayer graphene ribbons. By using a bias voltage perpendicular to the graphene bilayer we show how to get one-way charge and valley ...
Impurities and electronic localization in graphene bilayers
(American Physical Society, 2015-01-28)
We analyze the electronic properties of bilayer graphene with Bernal stacking and a low concentration of adatoms. Assuming that the host bilayer lies on top of a substrate, we consider the case where impurities are adsorbed ...
Structural, electronic, vibrational, and elastic properties of graphene/MoS2 bilayer heterostructures
Graphene/MoS2 van der Waals (vdW) heterostructures have promising technological applications due to their
unique properties and functionalities. Many experimental and theoretical research groups across the globe have
made ...
Enhancement of Fano-resonance response in bilayer graphene single and double barriers induced by bandgap opening
(Elsevier, 2020-05-10)
Fano resonances in bilayer graphene arise due to the coupling between extended and discrete electrons states, and represent an exotic phenomenon in graphene akin to Klein and anti-Klein tunneling, atomic collapse and ...
Photon-assisted transport in bilayer graphene flakes
(2017)
The electronic conductance of graphene-based bilayer flake systems reveals different quantum interference effects, such as Fabry-Perot resonances and sharp Fano antiresonances on account of competing electronic paths through ...
