Spin-resolved optical conductivity of two-dimensional group-VIB transition-metal dichalcogenides
Marco Gibertini, Francesco M. D. Pellegrino, Nicola Marzari +1
We present an ab-initio study of the spin-resolved optical conductivity of two-dimensional (2D) group-VIB transition-metal dichalcogenides (TMDs). We carry out fully-relativistic d…
Highly confined low-loss plasmons in graphene-boron nitride heterostructures
Achim Woessner, Mark B. Lundeberg, Yuanda Gao +10
Graphene plasmons were predicted to possess ultra-strong field confinement and very low damping at the same time, enabling new classes of devices for deep subwavelength metamateria…
Plasmon losses due to electron-phonon scattering: the case of graphene encapsulated in hexagonal Boron Nitride
Alessandro Principi, Matteo Carrega, Mark Lundeberg +4
Graphene sheets encapsulated between hexagonal Boron Nitride (hBN) slabs display superb electronic properties due to very limited scattering from extrinsic disorder sources such as…
Quantum capacitance and Landau parameters of massless Dirac fermions in graphene
Reza Asgari, Mikhail I. Katsnelson, Marco Polini
We present extensive numerical results for the thermodynamic density of states (i.e. quantum capacitance) of a two-dimensional massless Dirac fermion fluid in a doped graphene shee…
Generation and morphing of plasmons in graphene superlattices
Andrea Tomadin, Francisco Guinea, Marco Polini
Recent experimental studies on graphene on hexagonal Boron Nitride (hBN) have demonstrated that hBN is not only a passive substrate that ensures superb electronic properties of gra…
A stable path to ferromagnetic hydrogenated graphene growth
Shayan Hemmatiyan, Marco Polini, Artem Abanov +2
In this paper, we propose a practical way to stabilize half-hydrogenated graphene (graphone). We show that the dipole moments induced by an hexagonal-boron nitride (h-BN) substrate…
