Effects of citric acid on properties of single phase CuAlO2 thin films derived by chemical solution deposition

Preparation and Characterization of Solution-Processed Nanocrystalline p-Type CuAlO2 Thin-Film Transistors

“…Figure 1 a shows the XRD patterns of CuAlO 2 thin films annealed at a different temperature. For the film annealed at 700 °C, only weak CuO phase diffraction peaks at 35.8° and 38.9° were observed, indicating that 700 °C is not enough for the formation of CuAlO 2 phase [ 11 ]. Two new peaks at 31.7° and 37.1° assigned to CuAlO 2 and CuAl 2 O 4 phases, respectively, were observed after 800 °C annealing.…”

Dellafossite CuAlO2 film growth and conversion to Cu–Al2O3 metal ceramic composite via control of annealing atmospheres

“…Subsequent burn out of the complexing agent leads to a final porous material morphology with many holes in the film. 21 Recently it has been shown that CuAlO 2 films with excellent optical properties can be prepared by the interfacial reaction between Cu 2 O and sapphire substrates using a sandwich structure to inhibit the molten Cu x O from beading on the substrate surface due to surface tension. 22,23 For catalytic applications and for MCCs the use of sapphire is less desirable owing to its high cost and brittleness.…”

Effects of Mg substitution on the structural, optical, and electrical properties of CuAlO2 thin films

“…Since then, many attempts have been made to grow CuAlO 2 thin films with high performance (high conductivity and high transparency). Various production methods, such as pulsed laser deposition (PLD) [6], RF magnetron sputtering [7], chemical vapor deposition [8,9], spray pyrolysis [10,11], and sol-gel processes [12][13][14], among others, have been reported. Unfortunately, some difficulties, including high crystallization temperatures, secondary phase introductions, low transmittance, and low conductivity were encountered with these techniques.…”
