These proceedings from the November-December 2006 symposium including a representative cross-section of the broad range of papers and posters presented, reporting research on functional materials and devices. Topics include recent developments in light emission and photonic devices, including papers on advances in SiGeSn/Ge technology and multi-mode mid-IR silicon Raman amplifiers, Ge, SiGe, and diamond nanostructures, including a study of spin relaxation in SiGe islands and another on GeSi self-assembled islands for photonics application, strains and Si/Ge films, including strained Si-based nanomembrane materials, layer, including laser crystallization of silicon thin films using photo absorption layers formed by spin coating of carbon particles, Group IV nanowires, including the physics and materials of nanoscale transistors, and, of course, Si nanocrystals, including nonlinear properties and the effects of surface passivation on the stability of luminescence from nanocrystalline silicon particles in pure water.
