Topological Phases in Graphitic Cones

P. E. Lammert, V. H. Crespi

The electronic structure of graphitic cones exhibits distinctive topological features associated with the apical disclinations. Aharonov-Bohm magnetoconductance oscillations (perio…

Tuning Fermi-surface properties through quantum confinement in metallic meta-lattices: New metals from old atoms

J. E. Han, Vincent H. Crespi

We describe a new class of nanoscale structured metals wherein the effects of quantum confinement are combined with dispersive metallic electronic states to induce modifications to…

Dynamical effects of the nanometer-sized polarized domains in Pb(Zn1/3Nb2/3)O3

P. M. Gehring, S. -E. Park, G. Shirane

Recent neutron scattering measurements performed on the relaxor ferroelectric Pb[(Zn1/3Nb2/3)0.92Ti0.08]O3 (PZN-8%PT) in its cubic phase at 500 K, have revealed an anomalous ridge…

Substrate-mediated interaction on Ag(111) surfaces from first principles

Kristen A. Fichthorn, Matthias Scheffler

When two or more atoms bind to a solid surface, the substrate can mediate an interaction between them. In this paper, we use density-functional theory to quantify the substrate-med…

Polarization rotation via a monoclinic phase in the piezoelectric 92%PbZn1/3Nb2/3O3-8%PbTiO3

B. Noheda, D. E. Cox, G. Shirane +3

The origin of ultrahigh piezoelectricity in the relaxor ferroelectric PbZn1/3Nb2/3O3-PbTiO3 was studied with an electric field applied along the [001] direction. The zero-field rho…
