“…Nominally homogeneous polymers have been used in MIM devices, including true insulators such as polystyrene [36,37] and acrylates [36] as well as PVK [38] with its active side-group, and conjugated polymers such as thiophene derivatives, [39,40] polybiphenyls, [41,42] poly(spirofluorene), [43] and substituted poly(phenylene vinylene). [44] Combinations of functional components have been explored as potential storage media, most commonly electron donors and acceptors, motivated by the conductive properties of organic charge-transfer complexes.…”

Nonvolatile Memory Elements Based on Organic Materials

Many organic electronic devices exhibit switching behavior, and have therefore been proposed as the basis for a nonvolatile memory (NVM) technology. This Review summarizes the materials that have been used in switching devices, and describes the variety of device behavior observed in their charge–voltage (capacitive) or current–voltage (resistive) response. A critical summary of the proposed charge‐transport mechanisms for resistive switching is given, focusing particularly on the role of filamentary conduction and of deliberately introduced or accidental nanoparticles. The reported device parameters (on–off ratio, on‐state current, switching time, retention time, cycling endurance, and rectification) are compared with those that would be necessary for a viable memory technology.

“…55,56 One type consists of carbon-rich filaments formed by the local degradation of polymer films. 56,57 The other is associated with metallic filaments that result from the migration of electrodes through polymer films. 58,59 The production of metal filaments for filamentary conduction requires the use of polymers with both coordinating atoms and π-conjugation that can bind to metal ions regardless of the binding sites (side chain or main chain).…”

This review summarizes the most widely used mechanisms in high-performance polymeric resistive memory devices, such as charge transfer, space charge trapping and filament conduction. In addition, recent studies of functional high-performance polymers for memory device applications are reviewed, compared and differentiated based on the mechanisms and structural design methods used. By carefully designing the polymeric structure based on these systematically investigated switching mechanisms, almost all types of current memory characteristics can be reproduced, and these memory properties show extremely high endurance during long-term operation, which makes polyimides very suitable materials for memory applications. INTRODUCTION High-performance polymersToday, life without polymers is unimaginable. Polymers have become the major synthetic materials of the 21st century. High-performance polymers (HPPs) are particularly desirable. The synthesis and development of HPPs over the past 30 years have drawn the attention of many polymer scientists and investigators. These polymers generally possess excellent physical deformation resistance and chemical deterioration resistance at high temperatures over long periods of time. The quest for HPPs began in the late 1950s to meet the demands of the military, aerospace, machine-building and electronics industries, among many other industrial applications.Hill and Walker 1 first noted that the incorporation of aromatic segments into a polymer generally results in a notable increase in its thermal stability. For this reason, much of the research work has been directed toward aromatic compositions. Hence, HPPs usually tend to contain large numbers of aromatic units in their structures. Several of these aromatic HPPs have been used for commercial applications, such as aromatic polyamides, polyimides, polyesters, polysulfones, polytriphenylamine and heterocyclic polymers (Scheme 1). Aromatic polyamides (aramids) and polyimides, such as DuPont's Kevlar fiber and Kapton film, respectively, have been well known for a long time and constantly attract more interest than other HPPs for their useful properties, such as excellent thermal and oxidative stabilities, high mechanical strengths, low flammabilities and good chemical and radiation resistances. [2][3][4][5][6][7][8][9][10][11][12][13] However, the rigidity of the backbone and strong hydrogen bonding of these HPPs result in high melting or glass-transition

“…In this case the memory effect is attributed to electric field-induced charge transfer between the metal nanoparticles and the small organic molecules. Segui et al (1976) and Henish & Smith (1974) suggested that the switching mechanism (i.e. between the two conductivity states) in their devices is due to the formation of conductive filaments between the top and bottom metal electrodes.…”

Growth in the use of organic materials in the fabrication of electronic devices is on the rise. Recently, some attempts have been undertaken to manufacture polymer memory devices. Such devices are fabricated by depositing a blend (an admixture of organic polymer, small organic molecules and nanoparticles) between two metal electrodes. These devices show two electrical conductivity states ('high' and 'low') when a voltage is applied, thus rendering the structures suitable for data retention. In this paper, we describe an attempt to fabricate memory devices using ferroelectric nanoparticles embedded in an organic polymer. This paper also discusses issues related to the observed memory effect.
