Ya hemos dicho que las propiedades del silicio orgánico son similares desde el punto de vista químico a las del carbono, llegando al punto de que el silicio se necesita para la formación de las proteínas de los tejidos conectivos aunque esté presente en una pequeñísima cantidad.

The obtained values for the effective thermal effusivity of the porous samples diminished respect to the corresponding value of single-crystalline silicon, this decrease can be attributed to the restriction of the mean free path of phonons in the porous network. The samples were formed at room temperature in an electrolytic bath composed by a mixture of hydrofluoric acid ($48%$) and ethanol having a composition ratio of 1:1 in volume under potentiostatic condition (20 V) and an etching time of 2 minutes using back illumination provided by a laser beam with a wavelength of 808nm. The porous samples were obtained by means of photoelectrochemical etching of (100) $n$-type silicon wafers with different resistivity values, all in the range of 1-25 $\Omega$ cm. In this work using a theoretical fitting of the photoacoustic signal amplitude the effective thermal effusivity of porous silicon samples was determined.
The photoacoustic technique is a technique that studies the radiation-matter interaction through a well-known phenomenon as photoacoustic effect. Porous silicon, photoacoustic, thermal properties Abstract
