It has previously been shown that, in an electron-hole drop (EHD) produced in 〈11〉 -stressed Ge, a large population of electrons can be maintained in the strain-split-off (α3) electron valleys. The density and binding energy of these EHD are calculated on the assumption that the drops contain a single phase with a fixed ratio of α3 to α1 electrons. This ratio can be varied experimentally, and the observed densities as a function of α3 electron fraction are in good agreement with theory.
