Quantum Dot Photodetectors

Quantum Dot Photodetectors are devices that detect light using tiny semiconductor particles called quantum dots, which are a few nanometers in size. These dots can absorb specific wavelengths of light very efficiently, converting the light into electrical signals with high sensitivity and precision. Because their properties can be finely tuned by adjusting their size, quantum dot photodetectors offer advantages like faster response times, improved spectral selectivity, and potential for integration into various electronic systems. They are used in advanced imaging, communications, and sensing technologies, providing more accurate and efficient light detection than traditional photodetectors.
