Figure 3From: Silicon and Germanium Nanostructures for Photovoltaic Applications: Ab-Initio ResultsImaginary part of the dielectric function for the crystalline (top) and amorphous (bottom) embedded NCs, made by 10 (left), 17 (center), and 32 (right) atoms, respectively. For each plot a comparison of the responses of Si (dashed) and Ge (solid) NCs is provided (color online)Back to article page
