Uniform line and groove (L\/G) patterns on a PVDF thin film were imprinted using the soft imprint lithography (SIL) technique, followed by the deposition of a silver (Ag) electrode via DC magnetron sputtering. Structural and surface characterizations were performed using confocal Raman spectroscopy, X-ray diffraction, and atomic force microscopy. The Ag\/\u03b1-phase patterned PVDF\/Ag devices exhibited multiple transitions at set voltages (34.2 V, 37.9 V and 49.6 V in forward bias; \u221212.0 V and \u221215.6 V in reverse bias) and reset voltages (\u221227.5 V and \u221246.3 V in reverse bias; 50.0 V in forward bias) across different junctions than the unpatterned devices. Current-voltage (I\u2013V) characteristics revealed Ohmic conductivity at low fields, trap-filled space-charge-limited current (SCLC) at medium fields, and a transition to free-trap regimes at high fields, consistent with Geurst\u2019s trapped-SCLC model. These findings emphasize the potential benefits of \u03b1-phase PVDF thin films with L\/G structure by the SIL technique for resistive memory and flexible electronic applications.<\/jats:p>","DOI":"10.1021\/acsomega.6c04149","type":"journal-article","created":{"date-parts":[[2026,9,19]],"date-time":"2026-09-19T16:01:40Z","timestamp":1789833700000},"page":"58958-58971","source":"Crossref","is-referenced-by-count":0,"title":["Resistive Switching\nand Space-Charge-Limited Transport\nin Ag\/\u03b1-Phase Patterned PVDF\/Ag Devices Fabricated by Soft Imprint\nLithography"],"prefix":"10.1021","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1097-4602","authenticated-orcid":true,"given":"Ravisankar","family":"Muthuvel Sundaram","sequence":"first","affiliation":[{"name":"Prince of Songkla University, Pattani Campus , , ,","place":["Pattani, Thailand, 94000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bencha","family":"Thongnuanchan","sequence":"additional","affiliation":[{"name":"Prince of Songkla University, Pattani Campus , , ,","place":["Pattani, Thailand, 94000"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9367-8026","authenticated-orcid":true,"given":"Chatchai","family":"Putson","sequence":"additional","affiliation":[{"name":"Prince of Songkla University , , , ,","place":["Hat Yai, Songkhla, Thailand, 90112"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7743-7997","authenticated-orcid":true,"given":"Subhan","family":"Salaeh","sequence":"additional","affiliation":[{"name":"Prince of Songkla University, Pattani Campus , , ,","place":["Pattani, Thailand, 94000"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,19]]},"reference":[{"issue":"19","key":"2026100610481221400_cit1","doi-asserted-by":"publisher","first-page":"11392","DOI":"10.1021\/acs.chemrev.3c00196","article-title":"Smart and Multifunctional Materials Based on\nElectroactive Poly (Vinylidene Fluoride): Recent Advances and Opportunities\nin Sensors, Actuators, Energy, Environmental, and Biomedical Applications","volume":"123","author":"Costa","year":"2023","journal-title":"Chem.
