Temperature dependence of photoluminescence from self-organized Ge quantum dots with large size and low density

Photoluminescence（PL） from self-organized Ge quantum dots（QDs） with large size and low density has been investigated over a temperature range from 10 to 300 K using continuous-wave（CW） optical excitation.The integrated PL intensity of QDs observed is negligible at about 10 K and rapidly increases wi...
