Electronic shell and supershell structure in graphene flakes
M. Manninen, H. P. Heiskanen, J. Akola
We use a simple tight-binding (TB) model to study electronic properties of free graphene flakes. Valence electrons of triangular graphene flakes show a shell and supershell structu…

Sodium atoms and clusters on graphite: a density functional study
K. Rytkonen, J. Akola, M. Manninen
Sodium atoms and clusters (N<5) on graphite (0001) are studied using density functional theory, pseudopotentials and periodic boundary conditions. A single Na atom is observed to b…

Close-Packing of Clusters: Application to Al_100
K. Manninen, J. Akola, M. Manninen
The lowest energy configurations of close-packed clusters up to N=110 atoms with stacking faults are studied using the Monte Carlo method with Metropolis algorithm. Two types of co…
