Abstract

The influence of metal additives of catalysts introduced into the sensor material by sputtering platinum and palladium in the process of magnetron sputtering of tin dioxide on the gas-sensitive properties of semiconductor sensors to hydrogen sulfide vapors is established. The most significant increase in the sensor response to hydrogen sulfide vapor appears when adding 3% Pt.
