      abstract     = {Surface enhanced Raman spectroscopy (SERS) has been
                      established as a powerful tool to detect very
                      low-concentration bio-molecules. One of the challenging
                      problems is to have reliable and robust SERS substrate.
                      Here, we report on a simple method to grow coherently
                      embedded (endotaxial) silver nanostructures in silicon
                      substrates, analyze their three-dimensional shape by
                      scanning transmission electron microscopy tomography and
                      demonstrate their use as a highly reproducible and stable
                      substrate for SERS measurements. Bi-layers consisting of Ag
                      and GeOx thin films were grown on native oxide covered
                      silicon substrate using a physical vapor deposition method.
                      Followed by annealing at 800°C under ambient conditions,
                      this resulted in the formation of endotaxial Ag
                      nanostructures of specific shape depending upon the
                      substrate orientation. These structures are utilized for
                      detection of Crystal Violet molecules of 5 × 10−10 M
                      concentrations. These are expected to be one of the highly
                      robust, reusable and novel substrates for single molecule
                      detection.},
