Abstract

In the present work, porous silicon (PS) based Bragg reflectors are fabricated, and the reactive PS surface is passivated by means of thermal carbonization (TC) by acetylene decomposition. The gas sensing properties of the reflectors are studied with different gas compositions and concentrations.

Based on the results it can be concluded that thermally carbonized Bragg reflectors provide an easy and inexpensive means to produce chemically stable high quality PS reflectors with good gas sensing properties, which differ from those of unpassivated PS reflectors.

The acetone and methylamine induced spectral redshifts of the resonant wavelength are almost identical, as shown in graph a). However, the influence that the adsorbants have on the shape of the observed spectrum is totally different. Acetone widens the stopband, whereas methylamine has the opposite effect. This behaviour can be seen for the FWHM values recorded for the reflective stopbands, which are presented in graph b).

A correlation between the relative redshift and the saturated vapour pressure values was observed. Low value of the saturated vapour pressure leads to a higher sensitivity for the gas molecules.
