Abstract
In this letter, the resistive switching effects of one-dimensional PVDF in a geometry of Ag/ PVDF fibers/Ag and Ag/fibers’ pellet/Ag have been explored. Electrospinning has been utilized to fabricate PVDF fibers with the solution of Dimethyl Formamide (DMF)/Acetone (4:6) in the weight percentage of 12 wt% using the Far Field Electrospinnur method. Structure and microstructure are evaluated with Confocal Raman spectroscopy, X-ray diffraction Spectrometer, and Bruker MM8 Atomic Force Microscopy (AFM). A bipolar resistive switching with set voltage from 24 to 25 V, reset voltage from −12 to −15 V, and set voltage 26.5 to 30 V, reset voltage −28 to −15 V are observed for fibers and pellet respectively. Pellet has shown trap-filled space charge limited current (TSCLC) behavior, fibers show resistive switching, Ohmic, free and filled trap SCLC behavior, and obeys with Mott-Gurney's trapped SCLC model.
