Abstract

The present work represents the approach to develop the novel functional material for gas micro- and nanosensors. The isolated porous silicon arrays have been synthesized using the electrostatic mask method in the electro-chemical chamber. The hybrid material ‘carbon nanotubes-porous silicon’ has been synthesized on the isolated porous silicon arrays with the CVD process. The nanocomposite structure has been synthesized by tin sputtering on the hybrid material ‘carbon nanotubes-porous silicon’. The morphology and electro-physical properties of the nanocomposite structures have been investigated. The test gas sensor based on the nanocomposite structures showed high sensitivity to NO2 molecule absorption at room temperature.
