“…The Debye-Sherrer rings from inner to outer in the pattern can be consistently indexed to the (111), (200), (220), and (311) planes of face-centered cubic silver, respectively. Such observation is consistent with what has been reported elsewhere [25,26].…”

“…The intensity of the peak corresponding to the binding energy of Ag oxide increased, while that corresponding to Ag metal decreased (Figs. 5(c) and 5(d)), 21 indicating the formation of Ag oxide or hydroxide compounds during the dipping process. In particular, the Ag oxide peak increased considerably because of the spontaneous conversion of Ag hydroxides to Ag oxides.…”

We propose a facile method to control the growth and areal density of zinc-oxide (ZnO) nanowire arrays using gold or silver films deposited on aluminum-doped ZnO (AZO) layers coated on glass substrates. Nanowires exceeding 5 μm in length grew on both the glass/AZO-layer and on the glass/AZO-layer/Au-film where the areal array density was controlled primarily by changing the annealing temperature. In contrast, the nanowire arrays grew only on the AZO surface but not on the Ag film owing to the formation of an Ag-oxide layer. We fabricated field emitter devices with density controlled ZnO nanowire arrays and low turn-on electric field of ∼6 V/μm and a field enhancement factor of up to 1188 were obtained with density controlled ZnO nanowire arrays

“…The Ag 2−x O films were grown on r-plane sapphire substrates at room temperature by e-beam evaporation of Ag in the presence of an electron cyclotron resonance (ECR) oxygen plasma in a deposition chamber with base pressure b1 × 10 − 9 Torr; details of the deposition facility are given elsewhere [11,17]. The epitaxial grade r-plane (0112) α-Al 2 O 3 sapphire substrates acquired from Princeton Scientific were cleaned prior to deposition by exposing them to a 10 − 4 Torr ECR oxygen plasma for 30 min followed by heating for 30 min at 600°C in 10 − 4 Torr O 2 .…”

“…Other reported forms of silver oxide include the AgO, Ag 3 O 4 , and Ag 4 O 3 , and Ag 2 O 3 phases, all of which are less thermodynamically stable than Ag 2 O [7]. Silver oxide films (Ag 2 O and/ or AgO) have been fabricated over the past decade using several different techniques including magnetron sputtering [7][8][9], chemical bath deposition [10], ECR oxygen plasma assisted e-beam evaporation of Ag [11], and post-deposition oxygen plasma processing of Ag surfaces [12][13][14][15][16]. Because each of the silver oxide phases, including Ag 2 O, are relatively unstable in air and sensitive to contamination under different ambient conditions, there has been some disagreement about the exact stoichiometries, crystalline phases, and properties of silver oxide films.…”
