(https://creativecommons.org/licenses/by/3.0/) abstract: We report a study of the relationship between oxide microstructure at the scale of tens of nanometres and resistance switching behaviour in silicon oxide. In the case of sputtered amorphous oxides, the presence of columnar structure enables efficient resistance switching by providing an intial structured distribution of defects that can act as precursors for the formation of chains of conductive oxygen vacancies under the application of appropriate electrical bias. Increasing electrode interface roughness decreases electroforming voltages and reduces the distribution of switching voltages. Any contribution to these effects from field enhancement at rough interfaces is secondary to changes in oxide microstructure templated by interface structure. date: 2018-07-24 date_type: published publisher: Royal Society of Chemistry official_url: http://dx.doi.org/10.1039/C8FD00118A oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1565513 doi: 10.1039/C8FD00118A lyricists_name: Buckwell, Mark lyricists_name: Joksas, Dovydas lyricists_name: Kenyon, Anthony lyricists_name: Mehonic, Adnan lyricists_name: Ng, Wing lyricists_id: MBUCK33 lyricists_id: DJOKS24 lyricists_id: AJKEN86 lyricists_id: AMEHO63 lyricists_id: WHNGX78 actors_name: Kenyon, Anthony actors_id: AJKEN86 actors_role: owner full_text_status: public publication: Faraday Discussions issn: 1359-6640 citation: Kenyon, AJ; Munde, M; Ng, W; Buckwell, M; Joksas, D; Mehonic, A; (2018) The interplay between structure and function in redox-based resistance switching.
