Further investigation of lattice dynamics in low dimensional perovskite Cs2SnBr6

This sample has potential applications in LED applications, which requires an understanding of how the carriers interact with longitudinal phonons. It was measured this cycle on Merlin (and has an existing ERA), where evidence was found of several low energy transfer features. I would like to measure these more comprehensively as a function of temperature on MARI, which is better suited for <5meV features.
