Copper oxide nanostructured thin films processed by SILAR for optoelectronic applications

Area of Science:

• Materials Science
• Nanotechnology
• Solid State Physics

Background:

• High-performance p-type semiconductor oxides are crucial for advancing transparent and flexible electronics.
• Copper oxide (Cu$_{}$O) nanostructured thin films are attractive due to their p-type semiconductivity, transparency, non-toxicity, and low-cost fabrication potential.

Purpose of the Study:

• This review summarizes current research on Cu$_{}$O nanostructured thin films deposited using the SILAR technique.
• It aims to discuss the advantages of Cu$_{}$O, various deposition approaches, and the factors influencing SILAR-deposited films.

Main Methods:

• The review focuses on the SILAR (Successive Ionic Layer Adsorption and Reaction) technique for depositing Cu$_{}$O thin films.
• It examines fabrication parameters including precursor chemistry, pH, deposition cycles, annealing, doping, and growth temperature.

Main Results:

• The SILAR technique offers flexibility in substrate choice, large-area fabrication, cost-effectiveness, and low-temperature processing.
• Fabrication parameters significantly impact the structural, electrical, and optical properties of the resulting Cu$_{}$O nanostructured thin films.

Conclusions:

• Cu$_{}$O nanostructured thin films produced by SILAR are viable candidates for optoelectronic devices.
• Further research into SILAR-processed Cu$_{}$O is essential for optimizing their performance in next-generation electronics.
