Epitaxial Influence of Textured Conducting Metal Oxide Templates on Electrodeposited Ag(Ag3O4)2N03
ABSTRACTThe conducting oxysalt Ag(Ag3O4)2NO3 has been electrodeposited onto highly oriented conducting oxides of Tl2 03 and Pb0.8Tl0.2O1.9. T12O3 was grown in a [100] texture while the Pb0.8Tl0.2O1.9 was grown with two different thickness-dependent textures of [110] and [210]. The orientation of the Ag(Ag3O4)2NO3 crystals with respect to the substrate surface was determined by x-ray diffraction. The face-centered-cubic Ag(Ag3O4)2N03 crystals deposited on body-centered-cubic T12 03 and face-centered-cubic Pb0.8Tl0.2O1.9 followed the orientation of these prelayers. However, Ag(Ag3O4)2N03 which was electrodeposited onto polycrystalline 430 stainless steel had a nearly random orientation. The lattice mismatch is 6.6% between T12 03 and Ag(Ag3O4)2N03, and it is 7.8% between Ag(Ag3O4)2N03 and the doubled unit cell of Pb0.8Tl0.2Ol.9.
