Abstract
We demonstrate enhanced photoluminescence from Ge/SiGe quantum wells with strain from -0.28% (compressive) to 0.25% (tensile) achieved by epitaxial growth techniques. The intensity enhancement and peak shift from photoluminescence measurements are in agreement with theoretical calculations.
