TiO2 thin film gas sensor for monitoring ammonia
Systematic development and mechanistic studies of sensing materials are critical to the design of higher performance gas sensing elements and arrays. Polycrystalline metal-oxide semiconductors such as SnO2 and TiO2 are among the most widely used materials for thin film-based conductometric gas sensors. The mechanistic steps responsible for the gas-induced conductance changes of polycrystalline ...
متن کاملStress Considerations in Thin Films for CMOS-Integrated Gas Sensors
The integration of gas sensing elements into hand-held electronics will provide individuals the ability to detect harmful chemicals and pollutants in the environment in real time. Metal oxide gas sensors rely on changes in their electrical conductance due to the interaction of the oxide with a surrounding gas at an elevated temperature. The intrinsic stress in the metal oxide films during the l...
متن کاملElectronic structure and transport measurements of amorphous transition-metal oxides: observation of Fermi glass behavior
We characterized the conduction mechanisms in thin sputtered films of three representative binary Me–O (Me = Ta, W, and Nb) systems as a function of oxygen content, by combining in situ chemical state and electronic band structure studies from X-ray photoemission with temperature-dependent transport measurements. Despite certain differences, these amorphous films all displayed Fermi glass behav...
متن کاملInvestigation of reactions between trace gases and functional CuO nanospheres and octahedrons using NEXAFS-TXM imaging
In order to take full advantage of novel functional materials in the next generation of sensorial devices scalable processes for their fabrication and utilization are of great importance. Also understanding the processes lending the properties to those materials is essential. Among the most sought-after sensor applications are low-cost, highly sensitive and selective metal oxide based gas senso...
متن کاملEffect of Additives on Mn/SiO2 Based Catalysts on Oxidative Coupling of Methane
The Oxidative Coupling of Methane (OCM) over M-Na-Mn/SiO2 catalysts (M=W, Cr, Nb and V) was investigated using a continuous-flow quartz reactor at 775°C, 1 atm and 100 cm3min-1 gas flow rates, and correlated with the observed structure and redox properties.The interaction effects of the metal-metal and metal-support on the...
