We explore the accuracy of Vegard's law in determining the axial lattice constant, and investigate the intrinsic strain ... Webbetween Si and Ge. A Ge peak, centered at ~2100 nm, is evident in the photoluminescence spectra of these materials, which might result from direct band gap photoluminescence alone, or from superposition of direct band gap and indirect band gap photoluminescence. These Ge-on-Si materials are therefore promising in light emission applications.
