Electronic Structure of Negatively Curved Graphene
We study the electronic structure of graphene in the presence of either sevenfolds or eightfolds by using a gauge field-theory model. The graphene sheet with topological defects is considered as a negative cone surface with infinite Gaussian curvature at the center. The density of electronic states is calculated for a single seven-and eight-fold as well as for a pair of sevenfolds with differen...

متن کاملGraphitic Structure and Surface Chemical Activity of Nanosize Carbon Spheres
Monodispersed nanosize carbon spheres have recently been synthesized using a mixed-valent oxide-catalytic carbonization (MVOCC) process. In this paper, a high surface porosity of carbon spheres produced by an interaction with WO, is reported. The interaction mechanism is due to the reduction of WO, to W driven by an internal Auger decay process under the stimulation of a high-energy electron be...
متن کاملFirst-principles study on the electronic structure of Thiophenbithiol (TBT) on Au(100) surface
First principle calculations were performed using Density functional theory within the local spin density approximation (LSDA) to understand the electronic properties of Au(100)+TBT system and compare the results with Au(100) and bulk Au properties. Band structure, the total DOS and charge density for these materials are calculated. We found that the HOMO for Au(100)+TBT becomes broader than Au...
