Ca-doped Ceria Sputtering Targets

Ca-doped Ceria Sputtering Targets

Calcium-doped ceria (Ca-doped CeO₂) sputtering targets are used in the deposition of thin films for various advanced applications due to the unique properties imparted by the doping of ceria (CeO₂) with calcium (Ca). Here’s a detailed overview of the applications and benefits of Ca-doped ceria sputtering targets.

 Solid Oxide Fuel Cells (SOFCs)

Electrolyte Layers: Ca-doped ceria is commonly used as an electrolyte material in solid oxide fuel cells. The doping improves the ionic conductivity of ceria, making it suitable for high-performance fuel cell electrolytes. Sputtering targets made from Ca-doped ceria can be used to deposit these electrolyte layers, contributing to more efficient and durable fuel cells.

Catalysts

Catalytic Coatings: Ca-doped ceria can enhance the catalytic properties of ceria-based materials. In catalytic applications, such as automotive catalytic converters or industrial reactors, Ca-doped ceria sputtering targets can be used to deposit thin films that improve catalytic performance, including activities related to oxidation-reduction reactions.

 Sensors

Gas Sensors: Ca-doped ceria films can be used in gas sensors, particularly those for detecting gases like CO or NOx. The doping enhances the sensitivity and stability of the ceria films, making them effective for environmental monitoring and industrial process control.

Oxide Electronics

Electronics and Memory Devices: The improved ionic conductivity and stability of Ca-doped ceria make it suitable for use in various electronic devices, including memory devices and other oxide electronics. Sputtering targets can be used to deposit thin films for these applications.

Optical Coatings

Transparent Conductive Films: Ca-doped ceria can be used to create transparent conductive films, which are useful in optical coatings for touchscreens, displays, and other electronic devices. The doping enhances the electrical conductivity while maintaining optical transparency.

 Energy Storage

Supercapacitors: In energy storage devices like supercapacitors, Ca-doped ceria films can be used to improve performance by enhancing the material’s electrochemical properties. Sputtered films can contribute to higher capacitance and better energy storage capabilities.
