    Raman spectroscopy has been used to determine built-up deformation in GexSi1-x/Si strained-layer superlattice grown by molecular beam epitaxy. By comparing peak positions in commensurate superlattices and single layers with those from incommensurate thick layers of the same composition we can...

    Residual electrical resistivity measurement is employed to study dislocation storage under tensile loading of freestanding electroplated Cu films (1–5 μm grain size and 2–50 μm thickness). The results indicate that the nature of thickness effects (strengthening or weakening)...

    The Raman signal can be strongly increased for molecules deposited on a thin metal film in a configuration where the emission of the Raman signal into a glass support of the film is mediated by leaky surface plasmons (SPs). Here we show that SP provides an efficient pathway to detect tip...

    Temperature-dependent photoluminescence of MgZnO alloy film has been studied, and it is found that the emission intensity increases significantly at a certain temperature range and then decreases when increasing temperature further. The anomalous increase is resulted from the localized excitons...

    Visible laser irradiation of AgOx thin films forms Ag nanoparticles, which then results in surface-enhanced Raman scattering (SERS). The efficiency of this Ag nanoparticle formation strongly depends on the properties of the AgOx thin films. Thermal annealing causes changes in physical properties...

    Crack-free GaN films up to 11-μm-thick have been grown by using trenched SiC substrates and selective area metalorganic vapor phase epitaxy. These crack-free GaN films have hexagonal shapes and are surrounded by trenches. 97% of the hexagonal GaN films with side lengths of 100 μm and...
