NewsWise- The next generation imaging technology is expanding beyond smartphones in rapid intelligent equipment, robotics, extended reality (XR) devices, healthcare, CCTVs and various other industries. The origin of these technological progress is highly efficient, ultra-compact image sensors that convert light signals into electrical signals. Image sensors capture and process visual information from objects and environment, enabling the exact reconstruction of their size, size and spatial condition.
Currently, the commercial image sensors are mainly based on silicon semiconductors. However, research in the next generation image sensor is actively running using replacement-replacement for two-dimensional (2D) semiconductor nanomaterials-silicon. These nanomaterials, some nanometers made of atomicly thin layers are thick, offer extraordinary optical properties and miniature abilities, which are highly suitable for high-demonstration image sensors. However, maximizing their performance requires low resistance electrodes that are able to process optical signals efficiently. Traditional 2D semiconductor-based sensors face challenges in obtaining low resistance electrodes, resulting in poor optical signal processing efficiency, which has been a major obstacle for commercialization.
Do Cuong Hwang (Post-Silicon Semacist Institute, Ku-Kist Graduate School, Kisst School) and Dr. Minor Park (Post-Silicon Semiconductor Institute, Kist; University, and Yonesi University), Korea Institute of Science and Technology (Kissist, President, Sanyas-Club, Kevoche, President, Ghost (CBIC), CBIC, Ghost (CBIC), to get 2D semiconductor-converted images with high optical signal efficiency. By incorporating the nanopathy, the team significantly reduced its resistance, which led to sufficient improvement in the performance of the 2D semiconductor image sensor.
In particular, the team implemented this technique to successfully implement integral imaging-based imaging successfully on Dragonfly’s compound eye structure, three-dimensional (3D) imaging and glasses-free performance techniques. Using integral imaging technology, he acquired the acquisition and reproduction of RGB full—-let 3D images, enabling the recording and reconstruction of 3D object shapes. In the future, these high-demonstration image sensors are expected to be widely used in various advanced industries, including XR devices, Artificial Intelligence (AI) and autonomous driving systems.
Dr. Du Qung Hwang said, “By overcoming the technical boundaries caused by electrode issues in the current 2D semiconductor equipment, this research is expected to significantly accelerate the industrialization of the next generation imaging system technologies, which provide benefits in lighting absorption and miniatures.” He further emphasized the scalability of research, stating, “it is easy to spread and scalable developed electrode materials into large areas, which makes it widely applied to various semiconductor-based optoelectronic devices.” Dr. Min-Chaul Park said, “2D semiconductor-based optoelectronic devices that remove the challenge of Fermi Level Pinning will have a significant impact in industries that seek ultra-compact, ultra-hai-rugology and high-demonstration visual sensors in the future.”
