Cadmium Zinc Telluride: The Rare Semiconductor Material Transforming Medical Imaging and Security

Summary

The article focuses on cadmium zinc telluride (CZT), a rare and powerful semiconductor material that only a handful of companies worldwide can manufacture. It highlights how CZT is revolutionizing medical imaging, particularly in lung scans at Royal Brompton Hospital in London, where it has reduced scan times from 45 to 15 minutes. The material's unique properties allow for more precise radiation detection and imaging, with applications ranging from medical diagnostics to nuclear security and space exploration. The piece explores the technical challenges of producing CZT, its growing importance in various industries, and the geopolitical implications of its limited supply chain.
