CHALCOGENIDE GLASS IONIZING RADIATION SENSOR

摘要

A chalcogenide glass radiation sensor comprising a chalcogenide glass layer coupled to at least two electrodes and a metal source, and a method using the same are disclosed. The chalcogenide glass layer has a resistivity and the at least two electrodes are configured to facilitate the measurement of the resistivity of the chalcogenide glass layer. The coupling of the metal source and the chalcogenide glass layer is such that the resistivity of the chalcogenide glass layer changes upon exposure to ionizing radiation. The metal source is configured to be external to an electric field that may form between the at least two electrodes as the resistivity of the chalcogenide glass layer is measured.
