Experiment Title:
Performance and Structural Damage Analysis of Chalcogenide Glass Phase Change Temperature Sensors Under Ion Irradiation
Describe the work that you are proposing in detail. Please include as many specifics as possible (e.g., dose, dose rate, ion energy, types of ions, beam line x-ray energy, irradiation temperature, analysis temperature, atmosphere, etc.):
The samples have been prepared at Nanoionics Materials and Devices Lab at Boise State university (Total 24 samples. 12 fiber based and 12 electrical). Both thermally evaporated and printed devices will be used in this experiment. Half of the samples will be crystallized by heating at Boise State University. The devices will be irradiated in groups under vacuum (10^-8 Torr) at three different energies (200,500 and 1000keV) by Xenon (Xe+) ions in Michigan Ion Beam Laboratory. The expected dose would be 10^17cm^-2. The samples will be irradiated at room temperature, 530°C (Ge-Se systems) and 600°C (Ge-S systems). After irradiation, the sensor performance and change in crystallinity will be checked at Boise state. The Focused-ion-beam (FIB) and TEM system at Center for Advanced Energy Studies (CAES) will be used to study defect formation at the interface of the glass and substrate or fiber core. FIB lamella will be prepared for both pre- and post irradiated samples .
Technical Abstract
The goal of this project is to test the performance of the novel chalcogenide glass (ChG) phase change temperature sensors under irradiation. This study will reveal the impact of ion irradiation induced defects on device architecture, optical and electrical properties of chalcogenide glass in both amorphous and crystalline phases. Phase change chalcogenide glasses crystallize at certain temperatures, which is dependent on the composition. Changing of phase also changes the optical and electrical properties of the materials. To utilize this phenomenon, from the vast number of chalcogenide glasses, Ge-Se and Ge-S systems have been studied extensively for temperature sensing purpose in high radiation environment. These sensors are typically suitable for the monitoring of components with temperatures up to 500°C, although with specific adjustment of the composition of the material this sensor can become useful for metallic or ceramic SFR reactors where the cladding temperature can reach 650°C. This will provide a measurement method for multiple components in the reactor design domain of multiple reactors. The amorphous phase of ChG can be reversed by application of an electric field, thus facilitating multiple time use of the sensors. Besides, getting knowledge about the performance of the radiation hard waveguides in the reactor environment could extend their application to much more important characterization methods like for light transmission for in situ in-pile Raman spectroscopy. This experiment involves ion irradiation at different temperatures, optical, electrical characterization and transmission electron microscopy to study the effect of interfacial defects on device performance. This will provide crucial data about how the irradiation changes the optical and electrical properties of the material in both amorphous and crystalline phases. Although the amorphous phase under irradiation has been studied widely, not enough data is available for their crystalline phase. Upon satisfactory completion of the experiment, optical and electrical properties of a library of chalcogenide glasses in both phases will be obtained. It will help to understand certain device failure criteria and how the devices are going to perform when structural defects occur.
