Future Development Prospects of Cadmium Telluride (CdTe) Semiconductor Material

I. Revolutionary Potential in Medical Imaging Equipment

The application of cadmium telluride in medical imaging will drive the performance upgrade of nuclear medical equipment:

• Optimization of nuclear radiation detection and security inspection equipment: By enhancing the sensitivity and resolution of equipment for ray detection, it can reduce the dosage of radiation sources, ensuring detection accuracy while minimizing radiation hazards to the human body. This is particularly suitable for high-end medical devices such as PET/CT and SPECT.
• Highlighted value of core components in CT equipment: As a key material for high-precision infrared detection chips, its cost accounts for about 50% of the total value of CT equipment. With the development of medical imaging towards the direction of "low dosage and high resolution", cadmium telluride chips will become the core support for improving equipment performance, promoting the localization process of high-end medical devices.

II. Technological Breakthroughs and Application Expansion in Security Inspection

• Precise detection of hazardous materials: With high sensitivity and anti-interference capability, cadmium telluride detectors can carry out rapid spectral analysis of liquids, power banks, metal products and other items, accurately identifying inflammable and explosive substances or radioactive materials. Compared with traditional security inspection equipment (such as X-ray security inspection machines), it can reduce the false alarm rate and improve detection efficiency, suitable for public security scenarios such as airports, stations and customs.
• Miniaturization of mobile security inspection equipment: Due to its room-temperature working characteristics, cadmium telluride detectors can be integrated into handheld security inspection instruments or vehicle-mounted detection systems to meet the needs of mobile scenarios such as field and emergency security inspection, promoting the development of security inspection technology towards "portability and intelligence".

III. Two-way Breakthroughs of Infrared Products in Military and Civil Fields

• National defense and military industry field: Long-wave infrared detection is the core technology of night vision aiming, missile guidance and stealth target recognition. The wide bandgap characteristic of cadmium telluride material can realize high-sensitivity tracking of thermal targets, helping to upgrade infrared imaging seekers, shipborne infrared early warning systems and other equipment.
• Popularization in civil market: The maturity of uncooled infrared thermal imaging technology has promoted the application of cadmium telluride in civil fields, such as industrial equipment fault detection (power inspection, pipeline temperature measurement), security monitoring (forest fire prevention, perimeter alarm), consumer electronics (mobile phone thermal imaging modules), etc. With the decline of material costs, infrared thermal imagers are expected to transform from professional equipment
