Hydrogen profiles and resistivity of HxSmNiO3 upon distortions. a, b Hydrogen depth profiles for a SmNiO3/SrTiO3 and b SmNiO3/LaAlO3 in the 1% H2/He atmosphere after designed annealing durations. Black square: pristine SmNiO3; red dot: upon hydrogen annealing for 15 min; blue triangle: upon hydrogen annealing for 60 min c Hydrogen concentration after annealing for 15 min and d the respective enhancements of the resistivity, plotted as a function of the lattice distortions for SmNiO3 grown on different single crystal substrates of SrTiO3 (red), (La,Sr)(Al,Ta)O3 (blue), and LaAlO3 (black)
