Polarized micro-Raman spectroscopy was carried out on the (001) face of a 0.67PbMg(1/3)Nb(2/3)O(3)-33%PbTiO3 (PMN-33%PT) single crystal. The Raman images revealed the spatial variations of the intensity of the Raman bands, suggesting that the structu

Using magnetron cosputtering of SiO2, Ge, and Si targets, Si-based SiO2:Ge:Si films were fabricated for exploring the influence of Si target proportion (PSi) and annealing temperature (Ta) on formation, local structure, and phonon properties of nanoc

Gallium nitride (GaN) thin-films grown on sapphire substrates were lifted onto silicon wafer using a laser lift-off (LLO) process. The pulsed second harmonic (532 nm) Nd:YAG laser used in our LLO experiments had a photon energy (2.33 eV) much smaller

An ordered array of isolated alumina nanotubes was obtained using an anodizing method of Si-based Al films, which was composed of three steps: anodization of a Si-based Al film under a constant dc voltage in sulfuric acid to form a porous alumina fil

We have investigated the photoluminescence (PL) from anodic alumina membranes with an ordered nanopore array formed on bulk Al foils. Most of the membranes fabricated by anodization in oxalic acid showed a strong PL peak in the blue. Due to an obviou

ZrO2 nanograms annealed at different temperatures are systematically investigated using x-ray diffraction (XRD) and Raman spectroscopy. Our results show that bulk properties of nano-ZrO2 diminish but the defect-, surface-, and size-related features d
