Abstract
Polycrystalline n-type semiconducting metal oxides have been utilized as gas-sensing materials for the detection of toxic and flammable gases for many years. Although these devices can be highly sensitive to reducing gases, a frequent disadvantage is their lack of selectivity. However, work on zinc oxide has shown that using single crystals markedly improves the selectivity of the material to carbon monoxide. This paper reports a detailed investigation of the gas-sensing properties of other metal oxide single crystals, including tin oxide (SnO2), titanium oxide (TiO2) and iron oxide (Fe2O3), to CO, CH4 and water vapour.
