Electron–hole drops in -stressed germanium

We show, using the Mie theory, that the phase separation of electron–hole drops in [Formula: see text]-stressed Ge, predicted by Kirzcenow and Singwi, can be observed by the splitting of the plasma resonance into two components, a high frequency line arising from the dense, hot-electron component and a low frequency line from the low density shell. We also present extinction measurements on electron–hole drops that show that in samples with small drop radii the phase separation does indeed take place as predicted. Samples that contain large drops show the presence of hot electrons but the phase separation is difficult to observe by our technique.
