Abstract

The first absolute measurement of the density dependence of the enhancement factor g/sub eh/(0) for the electron-hole liquid in Ge is reported. This factor g/sub eh/(0) is a measure of the electron-hole spatial correlation function, and provides a valuable and sensitive test for the predictions of various many-body approximations. A strain-confined system of electron-hole--liquid and free-excitons is used. The data reported here agree quantitatively with the results of two different many-body--theory approximations.
