Comment on article "Line of Dirac Nodes in Hyperhoneycomb Lattices"
Marcos Veríssimo-Alves, Rodrigo G. Amorim, A. S. Martins
Recently, carbon hyperhoneycomb (-n) lattices have been proposed to be, through a one- orbital tight-binding (TB) model with nearest-neighbor (n.n.) hopping, a fami…
First-principles modeling of the thermoelectric properties of SrTiO/SrRuO superlattices
Pablo García-Fernández, Marcos Verissimo-Alves, Daniel I. Bilc +2
Using a combination of first-principles simulations, based on the density functional theory and Boltzmann's semiclassical theory, we have calculated the transport and thermoelectri…
Highly-confined spin-polarized two-dimensional electron gas in SrTiO/SrRuO superlattices
Marcos Verissimo-Alves, Pablo García-Fernández, Daniel I. Bilc +2
We report first principles characterization of the structural and electronic properties of (SrTiO)/(SrRuO) superlattices. We show that the system exhibits a…
Electromechanical Effects in Carbon Nanotubes
M. Verissimo-Alves, Belita Koiller, H. Chacham +1
We perform ab initio calculations of charged graphene and single-wall carbon nanotubes (CNTs). A wealth of electromechanical behaviors is obtained: (1) Both nanotubes and graphene…
Polarons in Carbon Nanotubes
Marcos Verissimo-Alves, R. B. Capaz, Belita Koiller +2
We use ab initio total-energy calculations to predict the existence of polarons in semiconducting carbon nanotubes (CNTs). We find that the CNTs' band edge energies vary linearly a…
