Abstract
The effect of approaching nozzle jet from the deposition surfaceon structural, optical and morphology properties of copper oxide thinfilms was studied. The film was prepared by homemade fullycomputerized CNC spray pyrolysis deposition technique atpreparations speed (3, 4, 5, and 6 mm/sec). The repeated line modewas used at deposition temperature equal 450 °C whereas thespraying time was in the range of (15-30 min) according to thedeposition speed. The film exhibit polycrystalline structure withpreferred orientation along (-111), (022) and (011), (002) at a 2θvalue of (35.63o) and (38.8o) respectively. Optical band gaps wererecorded 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) whichdepends on preparation speed.
Highlights
Different chemical depositions were used to prepare copper oxide (CuO) thin films
CuO have been prepared by using different techniques such as RF Plasma sputtering [8, 9], Radio Frequency(RF) Magnetron Sputtering [10,11], dc Magnetron Sputtering [12], active reactive evaporation [13], thermally oxidation [14] chemical and chemical vapor deposition [15, 16], Sol-gel [17], chemical spray[18,19]
CuO absorption layer can be used in wide range of application based on their properties and the examples include, the Magnetic behavior of copper oxide have been reported [20], CuO has been used as anode material of lithium-ion battery [5,6]
Summary
Different chemical depositions were used to prepare copper oxide (CuO) thin films. Spray pyrolysis deposition (SPD) was one of them.
