The Role of Cadmium Zinc Telluride (CZT) in Senso
Radiation Detection Function
Cadmium zinc telluride detectors are advanced radiation detection devices that can be used in sensors to detect X-rays and gamma rays. Their working principle lies in the special electrical properties of the cadmium zinc telluride material: when irradiated by radiation, it produces obvious changes in electrical signals, which are captured by the detector and converted into measurable electrical signals, thus enabling the detection of radiation. For example, in safety inspection sensors at public places such as airports and stations, it helps staff quickly and accurately detect carried radioactive materials; in sensors used in experimental research of particle physics, nuclear physics, etc. in the scientific research field, it provides a powerful experimental tool for scientists1.
As a Substrate Material for Infrared Detectors
Cadmium zinc telluride is a high-performance II-VI group compound semiconductor material. With different zinc contents, its band gap can be continuously adjusted, making it an excellent substrate for the mercury cadmium telluride material used to prepare infrared detectors. By performing corresponding material epitaxial growth and other processes on the cadmium zinc telluride substrate, infrared detector sensors with good performance can be prepared for applications in infrared detection-related fields23.
Boosting the Development of the Sensor Industry
In the sensor industry, cadmium zinc telluride crystals can be divided into three categories according to their product forms: single crystals, polycrystals, and thin films, each with different applications in the sensor field. Among them, polycrystalline cadmium zinc telluride crystals are mainly used in sensors and other fields; thin-film cadmium zinc telluride crystals have great market potential in the sensor industry due to their simple preparation process and low cost. In recent years, with the continuous development of nanotechnology, materials science, and semiconductor technology, the preparation technology and performance of cadmium zinc telluride crystals have been significantly improved, further promoting the development of the sensor industry.
