There is currently intense interest in the optical and electronic properties of nanometer-size
Si crystallites. In particular, strong visible photoluminescence from Si nanocrystallites …

This review is devoted to summarising the hydrogen-assisted properties and applications of
porous silicon (PS). The role of hydrogen as an intermediate product in silicon porosification …

It may be argued that silicon, carbon, hydrogen, oxygen, and iron are among the most
important elements on our planet, because of their involvement in geological, biol-ical, and …

Because of the rapid increase in commercially available Fourier transform infrared
spectrometers and computers over the past ten years, it has now become feasible to use IR …

We have studied the microstructure and optical properties of free-standing porous Si thin
films fabricated by electrochemical anodization. Raman-spectroscopy and transmission …

We show that first-principles electronic structure calculations of silicon wires with diameters
up to∼ 1.5 nm support the idea that quantum confinement and surface effects are …

The luminescence behavior of thermally oxidized porous silicon has been examined at
various temperatures and times. No blue shifting of the photoluminescence has been noted …

Highly efficient photoluminescence (PL) in the visible light range has been found in porous
Si (PS). The quantum confinement model (QCM) for the PL mechanism although explains …

The optical properties of porous Si films produced by electrochemical dissolution of Si are
reviewed. From measurements of the optical absorption spectra an inverse relationship …

Photoluminescence (PL) spectra of Si nanocrystals embedded in SiO2 films were measured
as a function of the size. Samples were prepared by rf cosputtering of Si and SiO2 and post …
