Journal ArticleDOI
Polaron lattice in highly conducting polyaniline: Theoretical and optical studies.
Sven Stafström,Jean-Luc Brédas,Arthur J. Epstein,H. S. Woo,David B. Tanner,W. S. Huang,Alan G. MacDiarmid +6 more
TL;DR: In this paper, the authors present optical-absorption data together with band-structure calculations for the polaron lattice and bipolaron lattice for the highly conducting form of polyaniline, proton-doped polyemeraldine.
Journal ArticleDOI
Negative Poisson's ratios as a common feature of cubic metals
TL;DR: In this paper, the authors found that negative Poisson's ratio is rare in crystalline solids and showed that the existence of positive Poisson ratios up to the stability limit of 2 for cubic crystals in the orthogonal lateral direction.
Journal ArticleDOI
Superhard and elastic carbon nitride thin films having fullerenelike microstructure.
TL;DR: In this article, the buckled and curved basal planes were found to have a distorted graphitel-like microstructure, and the buckling is due to the incorporation of pentagons in the basal planes, giving rise to a fullerenelike micro-structure.
Journal ArticleDOI
Effects of extrinsic and intrinsic perturbations on the electronic structure of graphene : Retaining an effective primitive cell band structure by band unfolding
TL;DR: In this paper, a band unfolding technique was used to recover an effective primitive cell picture of the band structure of graphene under the influence of different types of perturbations, which involves intrinsic p...

Materials with Negative Compressibilities in One or More Dimensions
Ray H. Baughman,Sven Stafström,Sven Stafström,Sven Stafström,Changxing Cui,Changxing Cui,Changxing Cui,Sócrates O. Dantas,Sócrates O. Dantas,Sócrates O. Dantas +9 more
TL;DR: Rare crystal phases that expand in one or more dimensions when hydrostatically compressed are identified and shown to have negative Poisson's ratios, which may be used to fabricate porous solids that either expand in all directions when hydroStatically compressed with a penetrating fluid or behave as if they are incompressible.
