Multilayers of Ge were deposited on (0 0 1) Si at low temperatures (250 and 300 C). The structural characterization was done by X-ray diffraction and reflectivity as well as by atomic force microscopy technics. The photoluminescence (PL) spectra reveal a quantum well (QW) emission that shifts to low
