Laser annealing of silicon clusters
A miniaturized pulsed laser-vaporization supersonic cluster beam source was developed and mounted on the magnetic axis of a Fourier transform ion cyclotron resonance apparatus (FT-ICR) so that the clusters were directly ...
Germanium clusters: More magic numbers
Clusters of silicon and germanium exhibit multiple isomers that can be annealed to single unique structural forms. The "magic number" reactivity trend observed for positive silicon clusters in the size range from 10 to 45 ...
