Single-layer metallicity and interface magnetism of epitaxial graphene on SiC(000)
I. Deretzis, A. La Magna
We perform density functional theory calculations for the determination of the structural and electronic properties of epitaxial graphene on 4H-SiC(000). Using commensurat…
Atomistic quantum transport modeling of metal-graphene nanoribbon heterojunctions
I. Deretzis, G. Fiori, G. Iannaccone +1
We calculate quantum transport for metal-graphene nanoribbon heterojunctions within the atomistic self-consistent Schrödinger/Poisson scheme. Attention is paid on both the chemical…
Electronic structure of epitaxial graphene nanoribbons on SiC(0001)
I. Deretzis, A. La Magna
We present electronic structure calculations of few-layer epitaxial graphene nanoribbons on SiC(0001). Trough an atomistic description of the graphene layers and the substrate with…
Insulator-metal transition in biased finite polyyne systems
A. La Magna, I. Deretzis, V. Privitera
A method for the study of the electronic transport in strongly coupled electron-phonon systems is formalized and applied to a model of polyyne chains biased through metallic Au lea…
Nonequilibrium electron charging in carbon-nanotube-based molecular bridges
Ioannis Deretzis, Antonino La Magna
We evidence the importance of electron charging under nonequilibrium conditions for carbon-nanotube-based molecular bridges, using a self-consistent Green's function method with an…
