Room temperature ozone sensing properties of p-type transparent oxide CuCrO2

Gas Sensing Properties of NiSb2O6 Micro- and Nanoparticles in Propane and Carbon Monoxide Atmospheres

“…Among the gases of which there is a broad interest for being monitored are oxygen (O 2 ), carbon monoxide (CO), carbon dioxide (CO 2 ), sulfur dioxide (SO 2 ), nitrogen oxides (NO and NO 2 ), hydrogen sulfide (H 2 S), methane (CH 4 ), ethanol (C 2 H 5 OH), and propane (C 3 H 8 ) [ [6,7], as well as the compounds LaFeO 3 , Mo 6 S 3 I 6 , and CuCrO 2 [8][9][10]. These materials are nowadays considered as extraordinary gas detectors because they possess good physical and chemical stability in different atmospheres.…”

Atomic layer deposition of transparent semiconducting oxide CuCrO2 thin films

“…Overall the recent optical measurements have found the direct optical bandgap to be in the range of 2.95-3.30 eV estimating CuCrO2 to be transparent to visible light. 20,21,22,23,24,25 It should also be mentioned that besides the TCO applications, CuCrO2 has attracted attention for a range of other applications, ranging from catalysis 26,27,28 and sensors 29,30 to thermoelectrics, 31,32,33 photocatalysis and removal of various hazardous gases 34,35 metal cations. 36 There are many methods available for the preparation of CuCrO2 thin films and coatings, such as reactive sputtering deposition, 37,38 pulsed laser deposition, 39,40,41,42 chemical solution deposition, 43,44,45,46 and molecular beam epitaxy.…”

Characteristics of CuCr1−xMgxO2 films prepared by pulsed laser deposition

“…the transition temperature (T c ) is about 120 K when Mn content is 20% [20]. CuCrO 2 bulks and films also show selective and reversible response to ozone at room temperature [21]. Besides delafossite films, another type of p-TCO thin film in the form of SrCu 2 O 2 has been synthesized by Kudo et al [22].…”
