Hydrogen doping of MgO thin films prepared by pulsed laser deposition

Epitaxial Thin Films of ATiO3–xHx (A = Ba, Sr, Ca) with Metallic Conductivity

“…After the hydride treatment, the colorless thin film changes to black regardless of the reduction temperature applied. Hydride reduction of thin-film oxides has been demonstrated previously, yielding SrFeO 2 , LaNiO 2 , and TiO 2– x from SrFeO 3 , LaNiO 3 , and TiO 2 , respectively, , but H – incorporation into oxide thin films beyond defect concentration levels has not been accomplished yet …”

“…Hydride reduction of thin-film oxides has been demonstrated previously, yielding SrFeO 2 , LaNiO 2 , and TiO 2−x from SrFeO 3 , LaNiO 3 , and TiO 2 , respectively, 14,15 but H − incorporation into oxide thin films beyond defect concentration levels has not been accomplished yet. 16 2θ−θ X-ray diffraction (XRD) measurements with Cu Kα radiation were performed at rt on both as-grown and hydridetreated films. XRD patterns of as-grown SrTiO 3 /LSAT film (Figure 1a) were indexed by (00l) reflections of SrTiO 3 , in addition to those from the substrate, indicating successful growth of epitaxial SrTiO 3 film.…”
