Title

Nature of hydride-ion mobility in peculiar perovskite oxyhydrides

Abstract

This proposal requests 8 days on IN16B, 7 days on IN11-C, and 4 days on IN6, to investigate the mechanistic aspects (relaxation times, activation energies, and spatial geometry) of hydride-ion mobility in a novel class of perovskite type oxyhydrides. Our investigations will focus on two sample compositions, BaTiO2.6H0.4 and BaTiO.2.9H0.1, and build on a recent (test) experiment at the backscattering spectrometer (HFBS) of the NCNR. Salient questions are: (i) what is the mechanism of H- dynamics in BaTiO3-xHx (x = 0.1 and 0.4) and how does it depend on the level of incorporated hydrogen (x)?, (ii) how is the mechanism of H- conduction related to H+ dynamics in classic perovskite type proton conductors?, and (iii) what can be learned towards a fundamental understanding of H transport in perovskite materials?
