Atomic layer deposition of SnO2 on In2O3 enables ultrasensitive NO2 detection at room temperature and DFT mechanism research

Construction of semiconductor nanocomposites for room-temperature gas sensors

“…Additionally, due to the low process temperature of ALD, it can be used to deposit on various substrate materials, including organic and sensitive materials. 160 ALD technology plays a crucial role in the manufacture of gas sensors. Because it can control the deposition of films at the atomic level, the sensors manufactured are highly sensitive and accurate.…”

High performance H2 sensors based on NiO-SnO2 nanosheets in temperature-pulsed operation mode

“…The slightly increased presence of surface adsorbed oxygen (O ads ) can act as donor impurities [33] incorporating more conductive chemisorbed oxygen species into SnO 2 upon NiO doping [34]. This phenomenon not only reduces the band gap energy [33], but also augments the adsorption capacity [35] and facilitates catalytic activity in the reaction with the target gas [36]. These favorable alterations may boost the H 2 sensing performance.…”
