Nishibori, MEMS Gas Sensors Based on Metal Oxide Nano Particles, CIMTEC2018 (14th International Ceramics Congress), 2018.06, For materials design of the semiconductor gas sensors, my group reported three important key factors, receptor function, transducer function and utility factor [1]. Such material designs are useful for devices in operating constant-heating. On the other hand, however, MEMS-type gas sensors in operating pulse-heating, which is one of the candidates for IoT sensors, need additional designs. So, we report new idea of materials and operation for MEMS-type gas sensors. SnO2 is typical sensor material, but the sensor in operating pulse-heating gives interesting sensing properties different from that of constant-heating. By pulse-heating in inflammable gas, the gas response was high at first 100ms and gradually reached to value obtained by constant-heating. The magnitude of first response was dependent on the concentration of inflammable gas (toluene). Furthermore, special additives to the sensing film gave enhancement in gas response [2].

Kengo Shimanoe, Yongjiao Sun, Koichi Suematsu, Ken Watanabe, Noriko Saito, Isao Sakaguchi, Reactive oxygen species on oxide semiconductors, GOSPEL WORKSHOP 2017, 2017.11, Semiconductor gas sensors for detecting inflammable gases generate signals in electric resistance by reaction of inflammable gases and oxygen adsorbed on metal oxides. In the case of SnO2, two kinds of oxygen adsorption species, O2- and O-, were reported. However, in 2013, we reported how two oxygen adsorption species were formed, and also it became clear that the influence of water vapor on sensor response was due to the change in oxygen adsorption species. To understand oxygen adsorption species on metal oxides is very important to obtain high sensor performance. In this presentation, we report oxygen adsorption species on various metal oxides under dry and humid conditions.
Table 1 shows oxygen adsorption species on various metal oxides and their modified oxides under dry and humid conditions. For neat-SnO2, the water vapor influences oxygen adsorption species. In short, dry air gives O2- at 350oC and wet air changes O2- to O-. Consequently, the thickness of space charge layer is reduced, and it brings a decrease in the electric resistance. In addition, the number of O- adsorption species is also decreased fairly. Therefore, the number of oxygen and electron to participate in a reaction with the inflammable gases decreases extraordinarily, and the sensor response lowers. However, such degradation in sensor response can be improved by surface modification and Pd-loading. The oxygen adsorption species remains O2- even in wet atmosphere although the number of adsorbed oxygen decreases. From these results, it is understood that such surface control is important for improvement of sensor response.
For other oxides such as In2O3 and ZnO, the oxygen adsorption species are also shown in Table 1. Interestingly, In2O3 gives O2- in both dry and wet atmospheres although the electric resistance in wet atmosphere decreases as compared with that in dry atmosphere. However, WO3 is in contrast to such oxides because oxygen adsorption species with negative charge, O2- and O-, were not observed. From the measurements of electric resistance under different oxygen partial pressure and the TPD (temperature program desorption), molecular-type oxygen (O2-) seems to adsorb on the surface of WO3 although such species doesn’t have strong oxidation power. However, WO3 shows ability for oxidation to inflammable gases. Therefore, it is thought that surface lattice oxygen participates in reaction with inflammable gases.
For practical use, we need materials design based on the understanding of oxygen adsorption species..

36. Kengo Shimanoe, Materials Design for Gas Sensors, Materials Colloquium in Seoul National University, 2016.09, Semiconductor gas sensors are widely used for detection of inflammable and toxic gases. To detect such low concentration gases, we have reported materials design including important three functions i.e. receptor function, transducer function and utility factor. Receptor function concerns the ability of the oxide surface to interact with the target gas. In addition, when the surface is loaded with a foreign receptor like PdO, it acts as a receptor stronger than the adsorbed oxygen. In addition, we found that small size of PdO (less than 3nm) shows high sensor response to inflammable gases even under humid condition. Transducer function concerns that the electron transport through the contact can thus be achieved by migration or tunneling of the surface electrons, indifferent to the bulk electrons inside. The device resistance is then inversely proportional to the surface density of electrons. Therefore the sensor response enhances with increasing oxygen partial pressure. For the utility factor, the target gas molecules diffuse the inside of a sensing body while reacting with the oxide surface. The above design and combination of three factors give gas detection in ppb level. However, for practical use, we must pay attention to water vapor poisoning. Under humid condition, it is well known that water molecules adsorbed on the surface give a large effects on the sensitivity and selectivity. For SnO2, the sensor response deeply concerns oxygen adsorption species which is O2- and O- in dry and wet atmosphere, respectively. To enhance the sensor response, we proposed importance of surface modification and nano-size Pd loading on SnO2. For surface modification, we found that Fe3+ and Sb5+ modifications gave O2- adsorption species under humid condition. In addition, Pd nano-size loading showed constant sensor response even by changing humidity. Those material designs are important for practical use, and should be introduced to MEMS gas sensors. In the presentation, the above will be shown..
