CZT (Cadmium Zinc Telluride) crystal bare die is a high-quality semiconductor material used for radiation detection, particularly X-rays and gamma rays. The bare die form refers to the crystal without any packaging, offering direct access to its sensitive surface for integration into custom detector assemblies. CZT crystals are valued for their high atomic number, room-temperature operation, and excellent energy resolution, making them ideal for medical imaging, security scanning, and spectroscopy applications.
