A large amount of work world-wide has been directed towards obtaining an understanding
of the fundamental characteristics of porous Si. Much progress has been made following the …

The use of porous silicon (PSi) as a sensor for detection of various analytes is reviewed. The
optical or electrical properties of PSi are key sensing parameters that have been used in …

The luminescence in the visible range of porous silicon is analyzed in the hypothesis of
quantum confinement. We calculate the electronic and optical properties of silicon …

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 calculated the electronic structure of spherical silicon crystallites containing up to
2058 Si atoms. We predict a variation of the optical band gap with respect to the size of the …

A blue-photoluminescence (PL) band, centered at 2.6 eV, was observed in thermally and
chemically oxidized light-emitting porous silicon layers with an efficiency that can exceed …

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

To improve the stability of porous Si (PS) prepared by electrochemical etching, we make use
of rapid-thermal oxidation (RTO). During RTO processing, the hydride coverage of the …

Porous silicon carbide has been fabricated using single crystal 6H‐SiC that has a wider
indirect band gap than silicon crystal. Intense blue‐green luminescence has been observed …
