Lanthanum distribution and dielectric properties of intergrowth Bi5−xLaxTiNbWO15 ferroelectrics
Bi5−xLaxTiNbWO15 x=0–1.50 ceramics prepared by conventional solid-state reaction were studied using x-ray diffraction XRD , dielectric spectroscopy and Raman scattering techniques. The XRD analysis implied that single-phase intergrowth bismuth layered perovskite structure was obtained for all the samples and when x=0.75, the Bi3+ in Bi2O2 2+ layer begins to be substituted by La3+. The dielectri...
متن کاملPlasmonic modes of annular nanoresonators imaged by spectrally resolved cathodoluminescence.
We report the observation of plasmonic modes of annular resonators in nanofabricated Ag and Au surfaces that are imaged by spectrally resolved cathodoluminescence. A highly focused 30 keV electron beam is used to excite localized surface plasmons that couple to collective resonant modes of the nanoresonators. We demonstrate unprecedented resolution of plasmonic mode excitation and by combining ...
متن کاملCarrier relaxation and recombination in an InGaN/GaN quantum well probed with time-resolved cathodoluminescence
Spatially, spectrally, and temporally resolved cathodoluminescence ~CL! techniques have been employed to examine the optical properties and kinetics of carrier relaxation for metalorganic chemical vapor deposition grown InGaN/GaN single quantum wells ~QWs!. Cathodoluminescence wavelength imaging of the QW sample revealed local band gap variations, indicating the presence of local In composition...
متن کاملHigh-resolution cathodoluminescence hyperspectral imaging of nitride nanostructures.
Hyperspectral cathodoluminescence imaging provides spectrally and spatially resolved information on luminescent materials within a single dataset. Pushing the technique toward its ultimate nanoscale spatial limit, while at the same time spectrally dispersing the collected light before detection, increases the challenge of generating low-noise images. This article describes aspects of the instru...
متن کاملLow-energy cathodoluminescence microscopy for the characterization of nanostructures.
Spatially and spectrally resolved low-energy cathodoluminescence (CL) microscopy was applied to the characterization of nanostructures. CL has the advantage of revealing not only the presence of luminescence centers but also their spatial distribution. The use of electrons as an excitation source allows a direct comparison with other electron-beam techniques. Thus, CL is a powerful method to co...
