Electric fieldTight-binding modelRandom-phase approximationThe collective excitations in AA-stacked bilayer graphene for a perpendicular electric field are investigated analytically within the tight-binding model and the random-phase approximation. Such a field destroys the uniform probability distribution of ...
On pristine graphene, the local gating applied by the tip induces a shift of the molecular levels of adsorbed molecules and can be used to control their charge state. Ab initio calculations show that under the application of an electric field, the hybrid molecule/graphene system behaves like an...
Electric-field-induced rich magneto-absorption spectra of ABC-stacked trilayer grapheneCondensed Matter - Materials ScienceCondensed Matter - Mesoscale and Nanoscale PhysicsThe magneto-optical spectra of ABC-stacked trilayer graphene are enriched by an electric field. A lot of prominent absorption peaks, ...
The single- and many-particle Coulomb excitation spectra in Bernal bilayer graphene can be modulated by a uniform perpendicular electric field. The field-induced oscillatory parabolic bands possess saddle points and local extrema, which, respectively, lead to logarithmically divergent peaks and ...
A vertical electric field is used to align the graphene sheets. Using this method, high﹒uality and vertically aligned graphene with a height of 18.7 m is obtained under an electric field of 30 V cm. TIMs constructed with the VG arrays exhibit a high vertical thermal conductivity of 53.5 W...

Here, active THz shielding and absorption properties of 3D graphene foam (GF) controlled by both laser pumping and biased electric field are investigated. The GF can be tuned from OFF-shielding state to ON-shielding state when the external field excitations are applied, and 10 dB shielding ...
