Cadmium zinc telluride (CZT) detectors represent a pivotal advance in radiation sensing technology, combining the high atomic numbers of cadmium and tellurium with a direct-conversion bandgap semiconductor structure that operates seamlessly at ambient temperatures. Unlike traditional germanium detectors that necessitate cryogenic cooling, CZT modules function proficiently in photoconductive mode at room temperature, delivering exceptional energy resolution and sensitivity across the X-ray and gamma-ray spectrum.

The inherent benefits of CZT arise from its direct bandgap, which spans from 1.4 to 2.2 electronvolts depending on composition, allowing for unipolar charge sensing via coplanar grid and small-pixel detector architectures that mitigate hole-trapping effects. A standard 1cm³ CZT crystal can achieve an energy resolution of 2.5% full-width at half-maximum (FWHM) at 662 keV, while larger pixelated volumes have demonstrated sub-1% FWHM resolution at the same energy, opening the door to precision spectroscopy and Compton imaging applications.

Over the last decade, CZT detectors have been integrated into cutting-edge medical imaging systems, notably in single-photon emission computed tomography (SPECT) cameras. Novel cardiac SPECT platforms employing pixellated CZT cameras exhibit higher count-rate capability and spatial resolution compared to NaI-based Anger cameras, reducing scan times and improving diagnostic confidence in nuclear cardiology.

Beyond healthcare, the NuSTAR astrophysics mission deploys CZT pixel detectors in its focal plane modules to capture high-energy X-ray photons from cosmic sources. Each NuSTAR detector array, comprised of four CdZnTe crystals with custom ASIC readouts, delivers photon counting at room temperature with minimal background noise, enabling transformative insights into astrophysical phenomena.

The landscape of cadmium zinc telluride detectors is undergoing rapid transformation as innovations in sensor architecture, readout electronics, and application breadth converge to redefine performance benchmarks across sectors. Advances in small-pixel geometries and coplanar grid designs have elevated unipolar charge collection, reducing polarization artifacts and enhancing energy resolution, which in turn supports emerging high-precision requirements in security screening and environmental radiation mapping.

Concurrently, the integration of photon-counting computed tomography systems using CZT modules has catalyzed a new era in medical diagnostics. Photon-counting CT scanners leverage CZT’s high photoelectric-to-Compton ratio to discriminate materials at each X-ray photon event, providing multi-energy data streams that fuel artificial intelligence-driven image reconstruction and contrast agent differentiation, thereby pushing diagnostic accuracy to unprecedented levels.

Space-qualifying efforts have further reshaped detector capabilities, exemplified by the TERI (Cadmium Zinc TElluride Radiation Imager) initiative slated for deployment on the International Space Station. TERI will validate large-volume CZT crystals under true space radiation conditions, probing degradation mechanisms while enabling Compton imaging of astrophysical gamma-ray bursts with 1.3% FWHM resolution at 662 keV.

Moreover, collaborative developments with NASA Goddard have yielded ultrathick, high-detection-efficiency CZT arrays for next-generation gamma-ray telescopes. These position-sensitive modules achieve sub-1% energy resolution at 1 MeV and submillimeter localization accuracy, setting performance milestones for missions aimed at mapping cosmic high-energy sources and probing fundamental physics in space environments.

The policy environment in 2025 has introduced a complex overlay of trade measures affecting the procurement and manufacturing economics of CZT detector components.
