New Design for Highly Sensitive and Fast DUV Detection

New Design for Highly Sensitive and Fast DUV Detection
In a study that was published in Advanced Materials, Prof. Shibing Long and his colleagues from the Chinese Academy of Sciences (CAS) University of Science and Technology of China (USTC) proposed a novel way to create a high-energy photon detector with fast response times and high sensitivity by combining the photoconductive and interface pyroelectric effects using a polycrystal Ga-rich GaOx (PGR-GaOx) Schottky photodiode.

Prof. Shibing Long and his colleagues from the Chinese Academy of Sciences (CAS) and the University of Science and Technology of China have developed a new high-energy photon detector with fast response times and high sensitivity. The detector, called a pyroelectric photoconductive diode (PPD), is based on a polycrystal Ga-rich GaOx (PGR-GaOx) Schottky photodiode and has shown exceptional sensitivity to deep ultraviolet (DUV) and X-ray, more than 100 times greater than previous detectors. The PPD also has the potential for use in imaging enhancement systems due to its low energy consumption and excellent sensitivity. This study not only reveals the promise of GaOx as a high-energy photon detector material, but it also proposes novel approaches for developing high-performance detectors. The findings were published in Advanced Materials.
