“…Most of the thin films deposited by sputtering, evaporation, CVD, PVD, or ALD techniques require a postannealing process to reorganize and stabilize the original non-crystalline structure [25,29,30]. Thus, the crosslinked networks were post-annealed at high temperature of 500°C in H 2 for 2 h. The change of grain size and surface roughness were hard to distinguish due to the poor conductivity of SnO 2 /NiO for SEM characterization, whereas the SAXS patterns shows more details of the crystallinity in Fig.…”

“…First, the traditional MOS thin films by MEMS techniques often show poor sensitivity to target gases due to the compact surface structure and low crystallinity. For example, Kang et al reported a sputtered Pt-doped SnO 2 thin film on microheater with a sensitivity of less than 4 to 25 ppm toluene at 450°C [29]. All the sputtered SnO 2 :NiO thin films in our previous research showed low sensor response of < 2 to 5 ppm NO 2 at 200°C before incorporating the selfassembled Au nanoparticle array [25].…”

“…In the literature, there are several examples of noble metals (Pd, Pt), rare earth metals (Ce, Pr), and metals (Zn, Al) improving the sensitivity and selectivity of various MOXs including SnO 2 [10,[12][13][14][15][16]. Among these materials, magnesium (Mg) is attractive, as it has proved to improve sensitivity to ethanol, H 2 , CO, and ammonia when incorporated into ZnO to form Mg-doped ZnO [17][18][19][20][21].…”
