High-K Dielectric barriers to suppress internal photoemission photocurrents
T2024-052
The Need
In an increasingly digital world, the demand for efficient and reliable photodetectors is paramount. These devices are critical for a variety of applications, from medical imaging to defense systems. However, traditional photodetectors often struggle with low UV-visible rejection, limiting their effectiveness.
The Technology
Introducing our new UV solar-blind photodetector. This innovative device leverages the ultra-wide bandgap material Ga2O3. While Ga2O3 typically suffers from low UV-visible rejection, our photodetector overcomes this challenge by incorporating a layer of high-K dielectric BaTiO3. The result is a photodetector with a UV-visible rejection ratio improved by five orders of magnitude.
Commercial Applications
- Medical Imaging: Enhanced UV detection capabilities can improve the accuracy and reliability of various imaging techniques.
- Optical Communications: With improved UV-visible rejection, data transmission can be more efficient and less prone to interference.
- Defense Systems: Enhanced UV detection can provide better surveillance and threat detection capabilities.
Benefits/Advantages
- Improved UV-Visible Rejection: Our photodetector offers a five orders of magnitude improvement in the UV-visible rejection ratio.
- Versatility: Suitable for a wide range of applications, from medical imaging to defense systems.
- Reliability: The use of robust materials like Ga2O3 and BaTiO3 ensures long-term performance and durability.
