Study of the dielectric properties near the band gap by VEELS: gap measurement in bulk materials

FPLAPW study of the structural, electronic, and optical properties of Ga2O3: Monoclinic and hexagonal phases

“…12 the energy loss function is plotted for ␤-and ␣-Ga 2 O 3 . The obtained spectrum of both structures are similar to that calculated by He and coworkers and to that of the experimental result [54]. The most prominent peaks a, b, c, and d in Fig.…”

“…[25]) are plotted as a red line. The experimental data taken from Schamm et al [54] are plotted as plus signs and scaled to match the calculated peak maximum. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of the article.…”

Structural and electrical properties of gold nanowires/P(VDF-TrFE) nanocomposites

“…The VEELS spectra were collected with an energy dispersion of 0.1 eV/channel, an illumination semi-angle α of 2.5 mrad and a collection semi-angle β of 6.5 mrad. The dielectric function was calculated using 'Epsilon' software performing deconvolution, angular correction, normalisation and Kramers-Krönig (KK) transformation successively [19]. Prior any quantitative analysis of the VEELS data, the spectrum was corrected for the point-spread function (PSF) of the instrumentation by a Fourier-ratio deconvolution and followed by a Fourier-log deconvolution to eliminate contributions from the plural scattering.…”

Imaging Si nanoparticles embedded in SiO2 layers by (S)TEM-EELS

“…The parameters of the model are 17.5 eV for the plasmon energy and 7.3 eV for the width of the Drude distribution. As in the case of the LI method, this treatment is also fast and user-friendly with an adapted version of the software EPSILON [20,21]. The LI and NNLS methods have been tested on several samples and they have been shown to provide similar results.…”
