Abstract
Photoluminescence spectra measured on a type-II quantum dot ensemble at high excitation power indicate a Mott transition from the low density state comprising of spatially indirect excitons to a high density electron-plasma state. Under the influence of a very high magnetic field, the electron-plasma that is formed at high excitation powers is transformed into magneto-excitons.
