The rational modification of porous and single‐crystalline silico surfaces is of particular
interest for technologies based on silicon. Porous silicon, such as the layer shown in the …

S ilicon is at the heart of the microelectronics revolution. Its dominance over other
semiconductors is intimately tied to its superior materials and processing properties and to …

The present state-of-the-art in understanding the mechanisms of the formation of porous
silicon (PS) and its physical properties is reviewed, with special emphasis on problems …

We have fabricated light-emitting diodes with a transparent doping layer on silicon
nanocrystals (nc-Si) embeded in silicon nitride matrix formed by plasma-enhanced chemical …

The properties and origins of the red, blue and infrared photoluminescence bands of porous
silicon are reviewed and discussed in the light of the models that have been proposed to …

We briefly review the performance to date of a variety of porous Si-based discrete
optoelectronic devices. Light emitting diodes, waveguides and photodetectors have now …

We report the realization of a bright and stable electroluminescent Schottky diode based on
aluminum‐porous silicon junction. White light, visible in normal daylight, is emitted when a …
