Photoluminescence Property of Nano-composite Phases of β-FeSi2 Nanocrystals Embedded in SiO2
Get PDFInternational Conference and Summer School on Advanced Silicide Technology 2014, July 19–21, 2014, Tokyo, JapanWe have investigated photoluminescence (PL) behaviors of nano-composite phase of β-NCs embedded in SiO2 (β-NCs/SiO2). The inhomogeneous spectra consisting of the A, B, and C emission bands were observed. PL enhancement also was confirmed in comparison with β-NCs/Si. Under high pumping rate, we observed PL spectra near room temperatures (~270 K). This fact means that oxidation of the nano-composite phase can contribute to reduction of thermal quenching, which may come from increase of band offsets around β-NCs
Electrical properties of fullerenol C60(OH)10/Au interface
Get PDFElectrical properties of the C60(OH)10/Au contact have been studied by measuring its current-voltage characteristics in the temperature range of 300–500 K. The Schottky barrier of the C60(OH)10/Au contact was confirmed to be 0.70±0.020.70±0.02 eV from Arrhenius plots of the current-voltage characteristics measured at various bias voltages as well as various preparation conditions of the C60(OH)10 material. Significant effect of the applied electric field on the barrier height has not been observed in the range of 0.1–2.0 MVm−10.1–2.0 MVm−1. The effects of both the charge transfer from C60 cage to OH groups and the crystallinity of the C60(OH)10 material on the Schottky barrier were discussed on the basis of x-ray photoemission spectroscopy and x-ray diffraction analyses
LiB electrode ageing observed from PVdF binder
Get PDFAgeing behaviors of the positive electrode of lithium ion battery are characterized by measuring mechanical properties of the electrode reeds, such as resonance frequency and internal friction, as a function of temperature. In the measurements of the electrode reeds with a sandwich structure of active material film and current collector of Al foil, two thermally-activated relaxation processes can be observed on the polyvinylidene difluoride binder in the active material film. Namely, a surface-related relaxation at ~150 K and a relaxation corresponding to the β-phase transition at ~240 K in the polymer binder can be observed at high signal/noise ratio. The resonance frequency decreases and the internal friction increases after charge/discharge cycling. The changes in activation energies of the relaxation processes also indicate that the measurement of mechanical properties of the positive electrode is an effective method for characterizing ageing behaviors of the positive electrode as a whole
