Reassignment of magic numbers for icosahedral Au clusters: 310, 564, 928 and 1426
Jan Kloppenburg, Andreas Pedersen, Kari Laasonen +2
Icosahedral Au clusters with three and four shells of atoms are found to deviate significantly from the commonly assumed Mackay structures. By introducing additional atoms in the s…
The (33)-SiC-() Reconstruction: Atomic Structure of the Graphene Precursor Surface from a Large-Scale First-Principles Structure Search
Jan Kloppenburg, Lydia Nemec, Björn Lange +2
Silicon carbide (SiC) is an excellent substrate for growth and manipulation of large scale, high quality epitaxial graphene. On the carbon face (the () or $(…
Ab Initio Bethe-Salpeter Equation Approach to Neutral Excitations in Molecules with Numeric Atom-Centered Orbitals
Chi Liu, Jan Kloppenburg, Xinguo Ren +3
The Bethe-Salpeter equation (BSE) based on GW quasiparticle levels is a successful approach for calculating the optical gaps and spectra of solids and also for predicting the neutr…
Sr3CrN3: a new electride with partially filled d-shells
Padtaraporn Chanhom, Kevin E. Fritz, Lee Burton +8
Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the a…
