investigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولX-ray absorption spectroscopy by full-field X-ray microscopy of a thin graphite flake: Imaging and electronic structure via the carbon K-edge
We demonstrate that near-edge X-ray-absorption fine-structure spectra combined with full-field transmission X-ray microscopy can be used to study the electronic structure of graphite flakes consisting of a few graphene layers. The flake was produced by exfoliation using sodium cholate and then isolated by means of density-gradient ultracentrifugation. An image sequence around the carbon K-edge,...
متن کاملContiguous petal-like carbon nanosheet outgrowths from graphite fibers by plasma CVD.
We report a catalyst-free synthesis of cantilevered carbon nanosheet extensions, or petals, from graphite fibers by microwave plasma CVD. Results reveal that the petals grow from the fiber surface layers while preserving graphitic continuity from fiber to the petals. Subtraction of Raman signatures from pristine and decorated fibers reveals a convolution of two underlying peaks at 2687 and 2727...
متن کاملSpectral theory and x-ray diffraction
where P(U) = J y p ( U’ + u) p( u’)~u’ is the autocorrelation of p; IN(s) is the measured intensity in the direction S, of radiation diffracted from a beam of wavelength A propagating in the direction Sc, with s= (S-&,)/A [Eq. (2.11) in Guinier].‘1&) clearly depends on the configuration of the given sample through P(U), and thus on the separations of scatterers and the relative frequencies of s...
