SXDT Advanced Materials Technology Co., Ltd. has 15 invention patents and has carried out industrialization of cadmium zinc telluride crystal materials, radiation detectors and imaging modules. It is the only one in China and the third in the world that can industrially produce and sell detector-grade CZT crystals and Companies related to detector products and equipment.
In 1895, the German physicist Roentgen discovered X-rays. Since then, high-energy ray detection and imaging have been developed and applied in many fields such as security inspection, nuclear medicine, astronomical monitoring, and industry. In the early 1990s, a compound semiconductor material that can work at room temperature and has high count rate, sensitivity, energy resolution and spatial resolution—cadmium zinc telluride (Cd1-xZnxTe, CdZnTe, CZT) began to be used. People know. As a semiconductor material with the best comprehensive performance in high-energy ray detection and imaging discovered for a period of time, it has attracted the attention of the team of Professor Jie Wanqi from Northwestern Polytechnical University in China.
Jie Wanqi`s team took the lead in China in 1994 to start the research and development of Cd1-xZnxTe crystal materials with X-ray and γ-ray detection and imaging as the application background. The team initiated the establishment of SXDT Advanced Materials Co., Ltd., with II-VI compound semiconductors and a new generation of radiation detector chips and modules as the main products, and the development goal of world-class radiation detection materials and device manufacturers to provide customers with radiation detection Materials and chip products and technical solutions in the field of imaging and imaging. SXDT has become the only company in China that produces and sells detector-grade cadmium zinc telluride crystals and related detector products and equipment.
The company`s existing mature products include CdZnTe crystals for X-ray and gamma-ray detectors and infrared epitaxial substrates, HgInTe crystals for near-infrared detectors, and HgMnTe crystals for infrared detectors and related devices. They are widely used in medical, industrial inspection, In security inspection and nuclear radiation inspection related fields, the products are exported to Europe and America.
