High temperature humidity sensors based on sputtered Y-doped BaZrO3 thin films

H2 gas sensor performance of NiO at high temperatures in gas mixtures

“…The NiO films were then annealed at 900 • C in synthetic air (80% N 2 , 20% O 2 ) for 5 h. The IDE structure is fabricated by liftoff photolithography and consists of a 20 nm thick titanium adhesion layer and a 230 nm thick platinum layer on top. The IDE is 250 m wide and the bond pad dimensions were one mm by one mm [7]. The IDE structure was used to measure the change in film resistance.…”

LCAO Calculations of (001) Surface Oxygen Vacancy Structure in Y-Doped BaZrO3

“…Such materials often exhibit significant oxygen-ion conductivity at elevated temperatures [1,2]. When such a material is exposed to a water vapor containing atmosphere at elevated temperatures, it can absorb water into the structure and consequently may become a proton conductor.…”

Nano‐ and microcrystals of doped niobates

“…The group of compounds, which has been intensively studied and presented in the literature, are perovskites like BaZrO 3 or Y-doped BaCeO 3 . These compounds are characterised by maximum proton conductivity of about 10 −2 S/cm [1][2][3][4]. The BaCeO 3 exhibits a relatively high protonic conductivity but is unstable in CO 2 atmosphere.…”
