Si nanoparticle-incorporated polyacrylonitrile (PAN) fibers are prepared using the
electrospinning method and Si-filled carbon (Si/C) fibers are obtained by the subsequent …

Carbon nanofiber-supported MnOx composites were prepared by electrodepositing MnOx
nanoparticles directly onto electrospun carbon nanofibers. The morphology and size of …

We apply a model dielectric function, which was developed for modeling the optical spectra
of crystalline semiconductors, to investigate the optical response in amorphous (a) …

Room temperature ferromagnetic hysteresis is observed in commercial SrTiO 3 substrates
purchased from a variety of suppliers. It is shown that the ferromagnetic signal comes from …

From TEM, XRD and Raman measurements, we compare the crystallization kinetics when
HWCVD and PECVD a-Si: H films, containing different initial film hydrogen contents (CH) …

The ability to crystallize thin amorphous Si layers into large grain Si can lead to significant
improvements in Si solar cells and thin-film transistors. Here we report on the effect of the …

Porous solids are very important from a scientific point of view as they provide a medium in
which to study the behavior of confined fluids. Although some porous solids have a well …

The authors report a study by small-angle x-ray scattering (SAXS) and tilting SAXS of
nanovoids in amorphous silicon films undergoing solid phase crystallization (SPC) by …

The viability of producing silicon nanoparticles using the HWCVD process is investigated. A
system is assembled and particles are produced from silane at pressures between 0.2 and …

Utilizing the concepts of a critical crystallite size and local film inhomogeneity, it is shown
that nucleation in thermally annealed hydrogenated amorphous silicon occurs in the more …
