Paper Abstract

This work reports first observation of a 2D-exciton luminescence in thin (8 - 25 nm) Ge layers of Ge-Ge1-xSix multiple quantum well structures grown on Ge [111] substrates. Photoluminescence spectra was studied at temperatures 2 - 300 K using a BOMEM DA3.36 Fourier-transform spectrometer with a cooled InSb detector, and use of a Nd:YAG laser radiation ((lambda) equals 1.06 micrometers ) for excitation. The shape of the luminescence spectral lines was corrected by black body calibration of the spectrometer.
