“…Following the first observations of switching behavior at Johns Hopkins, [45] Raman, [46] frequency dependent impedance, [47] optical, [48] IR, [48] and scanning electron microscopy (SEM) [49] measurements have been made with the goal of clarifying the mechanism. Some recent reports [49,50] start to address issues of device integration and performance. Other organic acceptors, for example AIDCN and ZnPc, have been coupled with Cu.…”

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.

“…For example, CuTCNQ nanoribbons can be grown via the selective reaction between tetracyanoquinodimethane (TCNQ) vapor and patterned Cu surfaces. [72][73][74] Devices can be prepared by patterning Cu/Au/Ti multilayer electrodes and then exposing the substrates to TCNQ vapor. CuTCNQ nanoribbons grown from two neighboring electrodes were observed to stretch toward each other and bridge the gap between electrodes.…”

Controlled Deposition of Crystalline Organic Semiconductors for Field‐Effect‐Transistor Applications

et al. 2009

The search for low‐cost, large‐area, flexible devices has led to a remarkable increase in the research and development of organic semiconductors, which serve as one of the most important components for organic field‐effect transistors (OFETs). In the current review, we highlight deposition techniques that offer precise control over the location or in‐plane orientation of organic semiconductors. We focus on various vapor‐ and solution‐processing techniques for patterning organic single crystals in desired locations. Furthermore, the alignment of organic semiconductors via different methods relying on mechanical forces, alignment layers, epitaxial growth, and external magnetic and electric fields are surveyed. The advantages, limitations, and applications of these techniques in OFETs are also discussed.

“…It is clear that nanowires grow only from regions that are coated with Cu, thus making it possible to pattern arrays of Cu-TCNQ nanowires into designs for their integration into devices with large numbers of parallel nanowires. [11] Raman spectroscopy has often been used to identify the vibrational modes resulting from different chemical bonds between metal atoms and TCNQ molecules in metal-TCNQ complexes.…”
