Temperature-resolved, in-situ powder X-ray diffraction of silver iodide under microwave irradiation

Abstract

Some unexpected properties of the ionic conductor, silver iodide, when heated by 2.45 GHz microwave radiation are investigated using temperature-resolved, in-situ powder X-ray diffraction. The lowering of the phase transition temperature can be explained by multi-phonon interactions with the microwaves and low-lying transverse optic modes.
