SUMMARY
Materials such as ZnO, SnO, and Pt exhibit high sensitivity to gases due to their unique electronic properties and surface reactions, while materials like Si, Ge, InP, and GaAs do not share these characteristics. Doping enhances the gas sensitivity of certain materials by introducing charge carriers that facilitate reactions with gas molecules. The paper titled 'Metal Oxide Gas Sensors: Sensitivity and Influencing Factors' provides comprehensive insights into these mechanisms and factors affecting sensitivity.
