| Abstract Scope |
Temperature sensing is a vital part of any nuclear reactor for its safe and efficient operation. However, due to harsh operating conditions (e.g. high radiation, temperature) the sensing materials degrade and make the sensors unreliable. In search of a reliable, lightweight and cheaper solution to this problem, a novel temperature sensor (up to 550°C) based on the amorphous-to-crystalline phase change property of chalcogenide glass (ChG) has been developed by inkjet printing. ChGs undergo amorphous-to crystalline phase change at a certain temperature and show high contrast in electrical resistivity (crystalline: low resistance mode) between two phases. Nanoparticle inks of ChGs (Ge-Se, Ge-S systems) were developed and both printing and thermal evaporation techniques were used to fabricate devices. This paper reports, for the first time an application of printed ChG as a temperature sensing material. Current-voltage characteristics of the as-fabricated printed and thermally evaporated devices have been analyzed to compare their performance. |
