“…This operating temperature is lower another work of Fe-based gas sensor [27]. The working temperature is affected by the thickness of the sample [28], [29], which is shown in Figure 6b). A thinner layer will widen depletion area and affect narrower area of electron mobility among the grains (Schottky contacts is higher).…”

This report aimed to know the performance of local mineral-based composite ceramic. The materials used consist of Indonesian local minerals, which are jarosite and manganite minerals as sources of oxide iron and Mangan. The materials were synthesized using the precipitation method, whereas composite ceramic was fabricated using a screen printing method and fired at 600 oC using a furnace. The results of the characterizations indicate that the sample forms three phases on diffraction peaks. The differences in the resistance values in ambient and ethanol environments indicate that the sample has very different responses. The high porosity of the sample greatly support the gas adsorption process. Thus, the sample has a high level of sensitivity. With the above characteristics, the composite ceramic which was fabricated has the potential to be applied to gas sensors, especially ethanol gas sensors.

“…Nanopartikel dari berbagai material seperti GaN, AlN, Si, InN, ZnO, BN, dan lain-lain telah dipelajari secara eksperimental dan teoritis [5]. Diantara material-material ini, ZnO termasuk semikonduktor oksida logam golongan II-VI karena seng dan oksigen berada pada tabel periodik ke-2 dan ke-6 [6]. Struktur kristal ZnO terdiri dari 3 bentuk, yaitu: hexagonal wurtzite, cubic zincblende, dan cubic rocksalt [7].…”

“…Jandow et al radio frequency sputtered the ZnO thin films of 300 and 600 nm thickness on the poly propylene carbonate (PPC) substrates and achieved better sensing response in the thinner ZnO film, which was assigned to the small particle size leading to the higher active surface area. [ 10 ] Dev et al used indium‐doped ZnO thin film for developing high‐sensitivity acetylene sensor which demonstrated 29.06 sensitivity at 100 ppm of acetylene at 150 °C. [ 11 ] In another interesting work, Vijayakumar et al spray‐coated Al‐, Fe‐codoped ZnO thin film and achieved a sensing response of 20 at 100 ppm of ammonia gas.…”

Herein, a facile and inexpensive ZnO thin film‐based carbon monoxide gas sensor is fabricated using a solution‐process technique. To vary the thickness of ZnO thin films, the precursor solutions of two different molarities, 3 and 5 m, are spin coated over glass substrates. The 3 m ZnO thin‐film device demonstrates more than two times improvement in sensing response as compared to 5 m ZnO films, for 50 ppm carbon monoxide concentration. Additionally, the 3 m ZnO film is found to perform better for low carbon monoxide concentrations, whereas the 5 m ZnO film shows a linear response over a wider range of carbon monoxide concentrations. The gas sensing mechanism and the impact of film thickness on the performance of the device are thoroughly studied and discussed, which may open the doors for the design and development of facile and high‐sensitivity metal oxide‐based gas sensors.
