The related rare-earth Ni-base perovskite compound (or hydrogenation rare-earth Ni-base perovskite compound) reported at present is in electronics
Application in terms of device is based primarily upon the variation that protium doping changes material static DC resistance.Such as by H-SmNiO3Make
For the channel layer (grid) of transistor, distribution of the proton in channel layer is controlled by electrode polarization, thus realize source electrode and
The adjusting variation of height configuration is shown in drain electrode.In contrast, for hydrogenation rare-earth Ni-base compound in strong dc electric field or alternating current
The practical application of nonlinear resistance reversible change due to caused by proton local migration there is no report under field action.We have found that
Migration occurs under the effect of certain activation energy and reduces and nickel oxygen octahedra for the proton mixed in hydrogenation rare-earth Ni-base compound
Bonding action, so as to cause material resistance nonlinear change.This characteristic makes the hydrogenatable non-linear electricity of rare-earth Ni-base compound
