A new breakthrough in infrared avalanche photodiodes (IR-APDs) promises to revolutionize the use of these devices in a variety of applications. Researchers from the National Institute of Information and Communications Technology (NICT) have developed a new type of IR-APD capable of operating in bulk 2D form, which enables the device to be more easily integrated into existing systems. This breakthrough could have a significant impact on applications such as medical imaging, security systems, and autonomous vehicles. The improved performance of these IR-APDs will allow for higher resolution images, improved detection distances, and faster response times.
