TL;DR: This article presents the projector augmented-wave (PAW) method as implemented in the GPAW program package using a uniform real-space grid representation of the electronic wavefunctions and implements the two common formulations of TDDFT, namely the linear-response and the time propagation schemes.
Journal ArticleDOI
Theory of Positrons in Solids and on Solid Surfaces
TL;DR: A review of the positron theory in solids and on solid surfaces is given in this article, which consists of three main parts describing the interaction processes, the theory and methods for calculating positron states, and selected recent results of positron studies of condensed matter.
Journal ArticleDOI
Interatomic interactions in the effective-medium theory

Journal ArticleDOI
Defect spectroscopy with positrons: a general calculational method
TL;DR: In this article, the positron potential is constructed from the full lattice electrostatic potential, and a local-density approximation for the correlation potential, in order to reliably predict annihilation characteristics for positrons trapped at defect clusters of varying size, geometry and impurity environment.
Journal ArticleDOI
Electron transport in edge-disordered graphene nanoribbons
Karri Saloriutta,Y. Hancock,Asta Kärkkäinen,Leo Kärkkäinen,Martti J. Puska,Antti-Pekka Jauho,Antti-Pekka Jauho +6 more
TL;DR: An electron transport study of lithographically fabricated graphene nanoribbons of various widths and lengths finds that charging effects constitute a significant portion of the activation energy.
