Nature of hydride-ion mobility in peculiar perovskite oxyhydrides
This proposal request 9 days on IN16B as well as 4 days on IN1-LaGrange to investigate the nature of hydride-ion diffusion and vibrational properties in the novel class of perovskite type oxyhydrides, BaTiO3-xHx (x = 0.1, 0.2, 0.3, 0.4, 0.5, and 0.6) as a function of both temperature and hydride-ion concentration (x). The specific questions are rather obvious: (i) what is the features/mechanism of hydride-ion dynamics and vibrational properties in perovskite oxyhydrides and how does it depend on temperature and hydride-ion concentration?, (ii) how is the mechanism of hydride-ion conduction related to proton dynamics in classic proton conducting perovskite type oxide analogous?, and (iii) what can be learned towards a fundamental understanding of H dynamics - now stretching from protic to hydridic species - in perovskite materials?
