Silicon shows photo-and electroluminescence at visible wavelengths when chemically
etched into a microporous network of 'wires' several nanometres thick. This raises the …

LIGHT-emitting devices based on silicon would find many applications in both VLSI and
display technologies, but silicon normally emits only extremely weak infrared …

Porous silicon has excited widespread interest since 1990, when its striking lightemitting
properties were first reported and ascribed to quantum size effects2. It is generally created …

MICROELECTRONIC device integration has progressed to the point where
complete'systems-on-a-chip'have been realized1–3. Now that optoelectronics is becoming …

FOLLOWING reports of intense optical luminescence from porous silicon1, 2, the opportunity
for engineering optoelectronic devices using this material3, 4 has attracted considerable …

The possibility induction of light emission from silicon, an indirect bandgap material in which
radiative transitions are unlikely, raises several interesting and technologically important …

This detailed electron microscope study of porous silicon compares the different structures of
macro-, meso-and microporous material. Mesoporous silicon of high porosity (∼-80%) …

We report resonantly excited photoluminescence (PL) spectroscopy of highly porous silicon.
In the PL spectra we observe satellite structure due to the participation of momentum …

The photoluminescence of porous silicon can be quenched by adsorbates, and the degree
of quenching can be tuned by chemical derivatization of the porous silicon surface. Thus, as …

Silicon light-emitting diodes (LED) show light emission at the bandgap energy of silicon with
efficiencies approaching those of standard III±V emitters: 0.1% for planar devices (our Letter) …
