Abstract

Synthetic Ag-doped PbS samples were Ar ion beam milled and examined by HRTEM. The silver was found to aggregate in inclusions which have no crystallographic relationship to the PbS host, rather than forming crystallographic defects. The ion beam milling process introduced a large number of small dislocations in both Ag-doped and pure PbS specimens. These dislocations are thought to be formed through coalescences of point defects. -from Authors
