Abstract
We have determined the radius and spatial distribution of electron-hole droplets in Ge at 2 K excited by a 100-mW focused beam of 5145-Å light. The droplet distribution can be approximated by a uniform hemispherical cloud of radius ≈ 1 mm containing droplets with radii of 2.0±0.5 μm. These results disagree with solutions of simple diffusion equations and with recent reports of the observations of single large droplets with radii ≈ 1 mm.Keywords
