The optical properties of oxidized free-standing porous silicon films excited by a cw laser have been investigated. It is found that samples oxidized at 800–950 °C show a strongly superlinear light emission at an excitation intensity of ∼10 W/cm 2.This emission has a peak at 900–1100 nm and shows a blueshift as the oxidation temperature is increased.

Feb 08, 2000 · Fig. 2 depicts the temperature dependence of the dark conductivity of porous Si films with different porosities. In this figure, as the porosity increases, the activation energy E a of the Arrhenius relation σ=σ 0 exp −E a / k B T increases, indicating that apparently the porosity has an influence on the charge transport mechanism, i.e. thermal excitation of carriers in the conduction. 8:30 AM A1.1/B1.1 HYBRID AMORPHOUS AND POLYCRYSTALLINE SILICON DEVICES FOR LARGE-AREA ELECTRONICS.
