Dynamic Properties of Inorganic Glasses

离子在无机玻璃中的运动将被研究。离子-离子相关（通过指数n）和所谓的两能级系统（TLS）参数将与材料特性有关。这将通过研究组成的系统变化对交流电和核自旋弛豫（NSR）行为的影响来完成。局域离子运动将用介电弛豫、NSR和离子热流来表征。这些技术与直流电导率和示踪剂扩散相结合，将允许对各种活化能进行关键的研究。

Ion motion in inorganic glasses will be studied. The ion-ion correlation (via exponent n) and the so-called two level systems (TLS) parameters will be related to material characteristics. This will be done by investigating the effect of a systematic variation of composition on ac electrical and nuclear spin relaxation (NSR) behavior. The localized ion movement will be characterized using dielectric relaxation, NSR, and ionic thermocurrent. These techniques combined with dc conductivity and tracer diffusion will allow a critical investigation of various activation energies.
