抄録

It was previously reported that the sintered transition metal oxides of the Ni-Mn-Co system could be used to detect atomic species of such common gases as hydrogen,de uterium, oxygen and nitrogen .Th e sensitivity for atomic beams correlates with the electrical resistivity of oxides, and its temperature dependence [Appl.Sun. Sci. 70nl(l993)351]. For the purpose of improving sensitivity for the atomic beam detection as well as getting more information on the reaction process of atomic beam with these sulfaces, ti was attempted to grow monocrystalline cobalt mono-oxides by the flame fusion technique and to examine their sensitivities. CoO single crystal sulfaces showed 103 times higher sensitivity than sintered polycrystalline surfaces.
