Controlling the Growth of Single Crystalline Nanoribbons of Copper Tetracyanoquinodimethane for the Fabrication of Devices and Device Arrays

Abstract

In this paper, (1) a simple and controllable method to synthesize single crystalline nanoribbons of CuTCNQ in a large area was demonstrated by using a physical and chemical vapor combined deposition technique. (2) Nanoribbons synthesized by this method were identified to belong to phase I. (3) Devices and device arrays of nanoribbons were in situ fabricated by this method using gap electrodes and gap electrode arrays. (4) Current-voltage characteristics of crystalline devices and device arrays of nanoribbons exhibited semiconductor properties, and this conclusion was further confirmed by the results of devices based on an individual nanoribbon or microribbon of CuTCNQ (phase I). The controllable synthesis of nanoribbons for the in situ fabrication of crystalline nanodevices and device arrays will be attractive for nanoelectronics. Moreover, semiconductor current-voltage characteristics of the nanoribbons will be beneficial to the understanding of CuTCNQ.

Selective Patterned Growth of Single‐Crystal Ag–TCNQ Nanowires for Devices by Vapor–Solid Chemical Reaction

“…The deterministic chemical vapor deposition (CVD) of inorganic nanowires from lithographically defined catalysis is currently a key focus for device fabrication. [2,3] However, organic nanomaterials with promising chemical/physical properties and functions are typically fabricated without catalyst assistance from the self-assembly of multifunctional molecules in solution, [4] physical vapor deposition, [5] or electrochemical templating methods. [6] The deterministic patterning of organic nanostructures has been reported only infrequently [7] and techniques similar to CVD have hardly been explored for the synthesis and patterning of organic semiconductor nanowires.…”

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

“…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.…”

“…CuTCNQ nanoribbons grown from two neighboring electrodes were observed to stretch toward each other and bridge the gap between electrodes. [72] As another example, Au nanoparticles can template the growth of F 16 CuPc 1D nanostructures through high-vacuum vapor deposition. The assembly of F 16 CuPc into uniform 1D nanostructures ($15-30 nm in diameter) was believed to be governed by thermodynamic forces together with kinetic parameters.…”

Morphological transition of a conductive molecular organization with non-covalent from nanonetwork to nanofiber

“…While there is a long history of development of this technique beginning with the studies on the optical and electronic properties of the LB films by Khun et al [3,4], direct observation of the folding of polymer chains in LB films using atomic force microscopy was a significant milestone, which revealed the phenomenon of ''morphogenesis at the interface'' [5,6]. For the several examples of ''morphogenesis at the interface'', the formation of nanofibers [7], nanowires [8,9], nanospheres [10], nanocoils [11], nanoribbons [12], sea-island structures [13,14], rods [15], gyroids [16], lamellae [17], and honeycombs [18] are noteworthy. Simultaneous control of the mesoscopic morphology (at the sub-micron level) of a non-covalent molecular organization, along with control of the molecular arrangement and packing structure (at the sub-nanometer level) are essential for the construction of next-generation quantum devices and medical materials.…”
