PbSe detectors are photoconductors with optimum response in the medium-wavelength infrared region. PbSe detectors provide fast response and high sensibility at room temperature, are rugged and show resistance to environmental conditions, providing lo

Lead selenide layers were obtained by thermal evaporation in vacuum on thermally oxidized silicon. As-deposited layers present no response to infrared radiation and an activation procedure is mandatory. The sensitization process described in this wor

The CO-TiO2(110) and SO2-TiO2(110) systems have been studied by electron-stimulated desorption (ESD) and Auger electron spectroscopy (AES). AES studies following CO and SO2 adsorption show clear differences. While the surface is unreactive for CO, i.
