FIG. 1.

[(a)–(d)] 2D conversion electron patterns emitted from in Ge around the ⟨111⟩, ⟨100⟩, ⟨110⟩, and ⟨211⟩ axes, following a annealing in vacuum. [(e)–(g)] Calculated patterns for Er-atoms occupying the T site and [(h)–(j)] the BC site around the ⟨100⟩, ⟨110⟩, and ⟨211⟩ axes respectively. [(k)–(n)] Best fits to the experimental patterns. The anisotropy is depicted with a color scale between red (low) and blue (high).

FIG. 2.

The experimental ⟨211⟩-pattern from Fig. 1(d) after subtracting the best fit when allowing a fraction on (a) the BC site, (b) the T site, and (c) both T and BC sites.

Image of FIG. 3.
FIG. 3.

Annealing temperature dependence of the fraction Er-atoms on the T site (circles) and the BC site (squares) for sample A (filled), B (open), and C (half open symbols). The dotted lines are a guide to the eye.
