Novel Chalcogenide Materials for x ray and Gamma ray Detection
Abstract
This project focused on exploring the potential of a new heavy atom chalcogenide family of semiconductors for room temperature gamma radiation detection. Its goal was to accelerate nuclear detector material discovery and development through innovative materials design/selection, synthesis and characterization. The project succeeded in expanding the currently small portfolio of potential materials. It allowed the assessment of fundamental limits for performance of the new materials. The project also focused in delineating clear relationships between material composition, structure and properties and the targeted performance and how they evolve from one material to the next. The close coupling of experiment and theory created an accelerated fundamental materials discovery effort which is greatly needed to develop the next generation radiation detector materials. The project investigated ternary chalcogenide semiconductors using selection criteria relevant to -ray detection at room temperature. These include heavy element composition, extended structures and wide energy band gap 1.8 < Eg < 2.5 eV.
