etching of silicon and production of Si nanostructures, in particular, Si nanowire arrays in …

We present results on the photoluminescence (PL) properties of silicon nanocrystals as a
function of their size. The nanocrystals are synthesized by laser pyrolysis of silane in a gas …

Well-aligned arrays of ZnO nanoneedles were fabricated using a simple vapor phase
growth. The diameters of the nanoneedle tips are as small as several nanometers, which is …

Silicon nanowires will find applications in nanoscale electronics and optoelectronics both as
active and passive components. Here, we demonstrate a low-temperature vapor–liquid …

Amorphous silicon nanowires (a-SiNW) with an average diameter of ca. 20 nm were
synthesized at about 950° C under an Ar/H2 atmosphere on a large area of a (111) Si …
