Ion Dynamics and Phonon Density of States of Oxyhalides and Oxides

In this project, we perform Phonon Density of States (PDOS) measurements to investigate the ion dynamics and PDOS in the interstitialcy migration of novel oxide-ion conductors Bi1.9Te0.1RO4.05X (R: rare earth such as Lu, X: halogen such as I). This proposal is a test measurement of MARI for the next proposal application (26-2). Its purpose is to determine whether the sample is measurable, to understand the spectrum obtained from the measurement, and to deepen our understanding of the measurement methods and environment of the samples.
