title = "Characterization of thallium-based ternary semiconductor compounds for radiation detection",
abstract = "We report on the characterization of optical and electronic properties of a series of thallium chalcogenide, wide gap ternary semiconductor compounds including Tl6I4Se, Tl6I4S, Tl 3SbS3, Tl2SnS3, and Tl 7Bi3I16 for ionized radiation detection at the x-ray and γ ray regimes. The semiconductor crystals were grown by the modified Bridgman method. The optical absorption, band gap, mobility-lifetime products for electron and hole carriers were measured at room temperature. For Tl6I4S and Tl6I4Se the mobility-lifetime products are comparable to those of CdZnTe. We measured room temperature detector response to x-ray and γ ray sources. For 137Cs radiation, Tl6I4Se has a well-resolved spectral response comparable to that of CdZnTe.",
