Plasmons in twisted bilayer graphene across dispersive and flat bands
Antonio Palamara, Michele Pisarra, Antonello Sindona
The dynamical dielectric response of twisted bilayer graphene is explored in large-angle dispersive-band and small-angle quasi-flat-band regimes using time-dependent density-functi…
Magic distances in twisted bilayer graphene
Antonio Palamara, Michele Pisarra, Antonello Sindona
Twisted bilayer graphene exhibits isolated, relatively flat electronic bands near charge neutrality when the interlayer rotation is tuned to specific magic angles. These small misa…
Engineering a Spin-Orbit Bandgap in Graphene-Tellurium Heterostructures
B. Muñiz Cano, D. Pacilè, M. G. Cuxart +13
Intensive research has focused on harnessing the potential of graphene for electronic, optoelectronic, and spintronic devices by generating a bandgap at the Dirac point and enhanci…
Spatial dispersion effects upon local excitation of extrinsic plasmons in a graphene micro-disk
Davide Mencarelli, Stefano Bellucci, Antonello Sindona +1
Excitation of surface plasmon waves in extrinsic graphene is studied using a full-wave electromagnetic field solver as analysis engine. Particular emphasis is placed on the role pl…
Acoustic plasmons in extrinsic free-standing graphene
M. Pisarra, A. Sindona, P. Riccardi +2
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers co…
