Abstract
The paper reported the fabrication of full organic resistive switch (FORS) with the sandwich structure of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)/poly(4-vinylphenol)(PVP)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS). The fabricated FORS elucidated reversible bipolar resistive switching behavior at higher operational voltage between -20 V and +30 V. The switching mechanism in the FORS device was attributed to the hole injection through PEDOT:PSS electrode and filling of trap sites in the PVP sandwiched layer by the limited injection. Current conduction mechanisms were concluded and supported by the charge transport governing physical laws. The dominant current conduction mechanism in the fabricated FORS was attributed to the transition from trap-limited space charge limited current (SCLC) conduction to trap-free SCLC conduction mechanism. The robustness of the fabricated FORS was tested over 100 multiple voltage sweeps.
