Fabrication and characterization of CuAlO2 transparent thin films prepared by spray technique

Effect of substrate temperature on the physical properties of dc magnetron sputtered CuAlO2 films

“…The optical band gap of the films decreased from 3.87 to 3.46 eV with the increase of substrate temperature from 373 to 573 K. The optical band gap of 3.46 eV at the substrate temperature of 573 K was found to be comparable with reported values of 3.5 eV by Kawazoe et al [3] in pulsed laser deposition, and 3.40 eV by Bouzidi et al [33] in spray technique.…”

The influence of substrate temperature on properties of Cu-Al-O films deposited using the reactive ion beam sputtering method

“…The main phase of CuAlO 2 starts to form only at high substrate temperatures. Cu-Al-O samples grown at the substrate temperature 380 °C have the bandgap values approximately near 4 eV, which correspond to the E g value of CuAlO 2 reported in the paper [11]. These hightemperature films have a good optical quality (transparency over 80% and abrupt band edge), which is important for TCO applications.…”

Fabrication of CuAl1−xMxO2 (M = Fe, Cr)/Ni film delafossite compounds using spin coating and their microstructure and dielectric constant

“…The thin film of CuAlO 2 via sol gel through dip coating has been reported by Ding, et al (2010) and Bouzidi, et al (2005).…”

“…Some of popular TCO material are simple or combined oxides as ZnO, ln 2 O 3 :Sn or ln 2 O 3 : Mo, etc. (Bouzidi, et al, 2005). So far we know the TCO are p-type semiconductors which is many limitation.…”
