摘要

The characteristics of an innovative chemical gas sensor device made of a macroporous silicon substrate hosting a thin layers of Sn-V mixed oxides ae presented .A wet permeatio technique has been used to induce co-precipitation of V and Sn oxohydrates providing a conformal coverage of the macroporous structure by the thin sensing film. The grain size and the chemical composition of the Sn-V polycrystalline oxide layer have been investigated and the experimental data are reported. Moreover, results on the sensitivity of a Sn-O-V permeated porous silicon device to C_6H_6 CH_3OH and CO gases are shown and compared.
