(a) Low-magnification image of hydrogen-doped ZnCoO thin film (Hpla3). (b) High-resolution transmission electron microscopy (TEM) image of the interface between the Hpla3 thin film and the Al2O3 substrate. (c) Energy-dispersive spectroscopy (EDS) compositional mappings of the Co, Zn, and O atoms in the yellow square area in (a) (scale bar indicates 200 nm).
