10. Kengo Shimanoe, Koichi Suematsu,Ken Watanabe, MEMS -Type Gas Sensor of Pd-Loaded SnO2 for Ultra-High-Sensitive Detection in ppt Level, 米国MRS FALL MEETING & EX HIBITE, 2019.12, Ultra-High-Sensitive gas detection in ppt level have been proposed by using pulse-heating of MEMS attached with Pd-SnO2. My group reported three important factors, receptor, transducer functions and utility factor, for gas sensor material designs and their integration in 2003 and 2006, respectively. In 2014, the gas sensor using Pd-SnO2 clusters based on the idea of the above integration could successfully detect toluene in ppb level. To enhance the sensor response more, we investigated the combination of utility factor and pulse-heating of MEMS. The MEMS-type gas sensors are repeatedly heated and allowed to cool by the application of voltage to the microheater; the target gas can penetrate into the interior of the sensing layer (Pd-loaded SnO2 clusters) during its unheated state. In 2018, we reported that such sensor responded to toluene in 0.1 ppb. In addition, the sensor response was found to increase by considering the oxygen adsorption state in the preheating and waiting-time before pulse-heating for measurement. The response of MEMS-type gas sensors showed a linearity to toluene concentration. It is found that the sensor response depends on the waiting-time between pre-heating and measure-heating. For example, in relationship of sensor response to gas concentration, the short waiting-time gave a steep slope, but the long waiting-time gave a gentle slope with lower detection limit. In the presentation, I will show the details as such Ultra-High Sensitive gas sensor..

45. Kengo Shimanoe, Design of semiconductor gas sensor toward detection in ppt level, The 12th International Conference on Ceramic Materials and Components for Energy and Environmental Applications (CMCEE-12) , 2018.07, [URL], For material design of semiconductor gas sensors, we reported receptor function, transducer function and utility factor [1]. By using integration of such three factors, the possibility of ppb-level detection was confirmed [2]. Now such high performance gas sensors are desired for an MEMS-type because of low power and compact devices. MEMS-type gas sensors are operated by pulse-heating mode. For such MEMS gas sensors, we propose that the combination of receptor function and utility factor is important. In the case of receptor function, surface reaction including oxygen adsorption on metal oxide is enhanced by increasing oxygen partial pressure using oxygen evolution materials [3]. In the utility factor, the sensor in pulse-heating mode gives interesting sensing properties different from that of constant-heating mode. The gas response in pulse-heating mode is high at first 100ms and gradually reached to value obtained by constant-heating. In this presentation, the details will be shown clearly.

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..

62. 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..
