| Popis: | A regular nanocomposite, consisting of 62 alternating Ag2Se and chalcogenide glass nanolayers of identical thickness, was fabricated by Pulsed Laser Deposition. The total thickness of the nanostructure is 700 nm. The Ag2Se layers in the nanostructure are amorphous in a wide temperature range, unlike the individual layers of this compound. A method for determining values of ionic and electronic conductivity components is proposed. It was found that the obtained nanostructure possesses high ionic conductivity at room temperature (≈10 Ω−1cm−1), which is comparable to the conductivity of superionic electrolytes. Synthesized nanostructures may find applications as solid electrolytes, as well as in the production of flexible electronics in combination with silver sulfide Ag2S. |
