✦ Synopsis

We present a microscopic understanding of the underlying physics that governs the photoluminescence spectrum at low electron densities. By performing near-and far-field measurements we show how the various characteristics of the spectrum (intensity, energy, width) are affected by the background electron density and the potential fluctuations due to the remote ionized donors.

A brief review of the theory of the ground state properties of the electron-hole system is presented, discussing the full density regime from isolated excitons to the electron-hole plasma. Particular attention is devoted to a discussion of coherent condensed phases, especially when excitonic recombi
