| abstract |
The present invention relates to the use, as a thin sensitive-material film for bolometric detection, of at least one material based on an alloy comprising at least one chalcogenide, said chalcogen element being chosen from sulfur, selenium, telluride and their mixtures, characterized in that said material furthermore contains a sufficient amount of carbon and/or boron to confer upon the material a temperature coefficient of resistivity value at 300° C. at least equal to 40% of the native value of the temperature coefficient of resistivity of said material at room temperature. The invention also relates to a bolometric device and its production process. |
