Effect of low level nozzle height on properties of copper oxide absorption layer prepared by fully computerized spray pyrolysis depositions

Abstract EN

The effect of approaching nozzle jet from the deposition surface on structural, optical and morphology properties of copper oxide thin films was studied.

The film was prepared by homemade fully computerized CNC spray pyrolysis deposition technique at preparations speed (3, 4, 5, and 6 mm / sec).

The repeated line mode was used at deposition temperature equal 450 °C whereas the spraying time was in the range of (15-30 min) according to the deposition speed.

The film exhibit polycrystalline structure with preferred orientation along (-111), (022) and (011), (002) at a 2θ value of (35.63o) and (38.8o) respectively.

Optical band gaps were recorded at these speed shows variance in value from (1.53-2.08 eV).

Films thickness were found to be in the range (128-412 nm) which depends on preparation speed.
