摘要： A detector for detecting radiation is generally described. The detector can comprise at least one ionic semiconductor material. For example, the ionic semiconductor material comprises a thallium halide and/or an indium halide. Electrical contacts are formed on the semiconductor material to provide a voltage to the detector during use. At least one of the electrical contacts may comprise a liquid that contains ions. In some instances, at least one electrical contact comprises a metal, such as Cr, Ti, W, Mo, or Pb. In some embodiments, the detector comprises both an electrical contact comprising liquid comprising ions and an electrical contact comprising a metal selected from a group consisting of Cr, Ti, W, Mo, and Pb. Detectors for detecting radiation, as described herein, may have beneficial properties.

摘要： Systems and methods for detecting radiation are generally described. The radiation detector comprises at least one semiconductor material, such as a thallium halide, that provides an electrical signal and optical signal upon exposure to a source of radiation. The electrical signal and optical signal may both be measured to detect the radiation.

摘要： A radiation detector is generally described. The detector can comprise a thallium halide (e.g., TlBr) and/or an indium halide. The thallium halide and/or indium halide can be doped with a dopant or a mixture of dopants. The dopant can comprise an alkaline earth metal element, a lanthanide element, and/or an element with an oxidation state of +2. Non-limiting examples of suitable dopants include Ba, Sr, Ca, Mg, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and/or Yb. Radiation detectors, as described herein, may have beneficial properties, including enhanced charge collection and long-term stability.
