Zinc Aluminum Oxide (ZnO/Al₂O₃ = 98/2 wt%) Sputtering Target

Transparent Conductive Oxide (TCO) Films

• Widely used in thin-film photovoltaic cells (e.g., CIGS, CdTe) and display technologies (LCD, OLED, touch panels) to create

• high-performance, cost-effective transparent electrodes.

• Offers excellent electrical conductivity, optical transparency (>80% in visible spectrum), and environmental stability

• compared to traditional ITO.

• 
  

1. Energy-Efficient Coatings

• Applied in low-emissivity (Low-E) glass for architectural and automotive windows to enhance thermal insulation and UV

• blocking while maintaining high visible light transmission.

• 
  

2. Gas Sensing Devices

• Utilized in semiconductor-type gas sensors (e.g., for H₂, NO₂, CO detection) due to its high surface reactivity and tunable

• electrical properties under gas exposure.

• 
  

3. Anti-Reflective & Protective Coatings

• Deployed in optical components (lenses, solar panel surfaces) to minimize reflection losses and improve durability

• against environmental degradation.

• 
  

4. Flexible Electronics

• Enables fabrication of bendable transparent circuits for wearable devices, foldable displays, and flexible sensors,

• leveraging its mechanical resilience and low-temperature deposition compatibility.

• 
  

5. Piezoelectric Applications

• Serves in surface acoustic wave (SAW) filters, actuators, and energy harvesters, capitalizing on ZnO's inherent

• piezoelectric properties enhanced by Al₂O₃ doping.

• 
  

6. Advanced Optoelectronics

• Integrated into photodetectors, UV sensors, and light-emitting diodes (LEDs) for its wide bandgap (~3.3 eV)

• and tunable optoelectronic responses.
