An important parameter that should be considered for diodes used in RF rectifier is the turn on voltage, which should be low to overcome the problem of the low voltage generated and power extracted from energy harvesting.\u0000In this work, we focused on pentacene organic rectifier with high rectification ratio and low threshold voltage obtained by tuning the work function of gold with a self-assembled monolayer of PFBT and optimizing the thickness of the organic layer. We demonstrate a high rectification ratio up to 107 and a very low turn on voltage as low as 20 mV. Flexible rectifier diode have been also fabricated in release paper WO84, high rectification ratio of 106 was obtained even after bending of the device. The pentacene based rectifier diodes were also demonstrated to operate at more than 1GHz. This provides a great potential for fabricating high-performance organic flexible diodes and opens the way for the development of high frequency response using organic materials.\u0000\u0000References \u0000[1] D.

In such ECM systems, the formation of conductive filaments (CFs) is typically composed of two activation steps: i) the electrochemical redox reactions at an interface between an electrode and an electrolyte and ii) the migration of the cations of metal across the electrolyte. Accordingly, the overall electrical performance of the ECM device is primarily governed by the kinetics of the two steps. However, in the ECM devices using organic electrolytes, a rather compete picture of the resistive switching during the ion-migration process has not been described so far since filamentary paths are barely observable.\u0000\u0000 In this work, we investigated how the resistive switching depends on the ion-migration properties including the drift velocity and the migration path in the organic ECM device. Two types of polymer electrolytes, having different molecular weights, were used for the control of the ion drift velocity. The topography of ion-migration paths was modified by the deposition rate of metal for the top electrode. The formation and the retention of the CFs depend critically on the ion mobility of the polymer electrolyte and the topography of the ion-migration paths as well. These results will provide a useful guideline for constructing high- performance ECM storage systems based on organic materials.\u0000\u0000This work was supported by the Brain Korea 21 Plus Project in 2018.","PeriodicalId":366222,"journal":{"name":"Organic and Hybrid Sensors and Bioelectronics XI","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130930883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
