Abstract
Copper contamination from dilute aqueous solutions has previously been shown to produce fast surface states on germanium. These states comprise a recombination center close to midgap, with large capture cross sections for both electrons and holes, and trapping states at about 0.2 eV above and below midgap. The states are attributed to copper metal microcrystals that deposit on the surface.Keywords
