“…Recently these techniques have been utilized to assemble nanowires. For instance, cross-nanowire circuits have been reported based on organic single-crystal copper phthalocyanine (CuPc, p-type), copper hexadecafluorophthalocyanine (F 16 CuPc, n-type) and inorganic Sb-doped tin dioxide (SnO 2 :Sb) nanowires. 29 Device fabrication was carried out with microprobes on a micromanipulator probe station.…”

“…2a and b, first, a layer of poly(methyl methacrylate) was spin-coated onto the substrate as a gate insulator. Second, organic single-crystal nanowires of CuPc or F 16 CuPc were transferred onto the polymer gate insulator by means of nano-mechanical manipulation. Third, SnO 2 nanowires were transferred to contact the CuPc and F 16 CuPc nanowires, serving as source and drain electrodes.…”

“…[7][8][9][10][11][12][13][14][15][16][17] Generally, there are two main strategies for the assembly of nanowire devices: (1) transfer with alignment of pre-grown nanowires onto a desired substrate; (2) direct growth of aligned nanowires or nanofibers onto a desired substrate even at desired locations. In this review article, we summarize recent advances in large-scale nanowire assembly technologies, including flow-assisted alignment, Langmuir-Blodgett technique, contact/ roll printing techniques, bridging method, and electrospinning, etc.…”

Recent advances in large-scale assembly of semiconducting inorganic nanowires and nanofibers for electronics, sensors and photovoltaics

Semiconducting inorganic nanowires (NWs), nanotubes and nanofibers have been extensively explored in recent years as potential building blocks for nanoscale electronics, optoelectronics, chemical/biological/ optical sensing, and energy harvesting, storage and conversion, etc. Besides the top-down approaches such as conventional lithography technologies, nanowires are commonly grown by the bottom-up approaches such as solution growth, template-guided synthesis, and vapor-liquid-solid process at a relatively low cost. Superior performance has been demonstrated using nanowires devices. However, most of the nanowire devices are limited to the demonstration of single devices, an initial step toward nanoelectronic circuits, not adequate for production on a large scale at low cost. Controlled and uniform assembly of nanowires with high scalability is still one of the major bottleneck challenges towards the materials and device integration for electronics. In this review, we aim to present recent progress toward nanowire device assembly technologies, including flow-assisted alignment, Langmuir-Blodgett assembly, bubble-blown technique, electric/magnetic-field-directed assembly, contact/roll printing, planar growth, bridging method, and electrospinning, etc. And their applications in high-performance, flexible electronics, sensors, photovoltaics, bioelectronic interfaces and nano-resonators are also presented.

“…The integration of transducing platforms and material synthesis methods is an essential phase for VOC sensors’ scalability and large production. Such integration can mostly be achieved by direct or transfer methods [ 140 , 142 ]. The first (direct method) involves the selective deposition of the material over the transducing platform.…”

VOCs Sensing by Metal Oxides, Conductive Polymers, and Carbon-Based Materials

et al. 2021

This review summarizes the recent research efforts and developments in nanomaterials for sensing volatile organic compounds (VOCs). The discussion focuses on key materials such as metal oxides (e.g., ZnO, SnO2, TiO2 WO3), conductive polymers (e.g., polypyrrole, polythiophene, poly(3,4-ethylenedioxythiophene)), and carbon-based materials (e.g., graphene, graphene oxide, carbon nanotubes), and their mutual combination due to their representativeness in VOCs sensing. Moreover, it delves into the main characteristics and tuning of these materials to achieve enhanced functionality (sensitivity, selectivity, speed of response, and stability). The usual synthesis methods and their advantages towards their integration with microsystems for practical applications are also remarked on. The literature survey shows the most successful systems include structured morphologies, particularly hierarchical structures at the nanometric scale, with intentionally introduced tunable “decorative impurities” or well-defined interfaces forming bilayer structures. These groups of modified or functionalized structures, in which metal oxides are still the main protagonists either as host or guest elements, have proved improvements in VOCs sensing. The work also identifies the need to explore new hybrid material combinations, as well as the convenience of incorporating other transducing principles further than resistive that allow the exploitation of mixed output concepts (e.g., electric, optic, mechanic).

Local CuO Nanowire Growth on Microhotplates: In Situ Electrical Measurements and Gas Sensing Application

et al. 2016

We report on local CuO nanowire growth on microhotplates combined with in situ measurement of the electrical resistance for well-controlled integration into conductometric gas sensing devices. Discrete current steps were observed during the CuO nanowire synthesis process, which is attributed to individual nanowire connections being formed. The high gas sensitivity of the CuO nanowire devices was confirmed by detection of carbon monoxide CO in the low ppm-level concentration range. Furthermore, we demonstrate that CuO nanowire growth inside a gas measurement setup allows studies on gas sensor poisoning/deactivation processes. A significant decrease of CO response was found after controlled exposure to humidity, which suggests sensor deactivation by surface hydroxylation. Thus our approach could be a novel and simple way for revealing new insights in various gas sensor degradation mechanisms in the future and might be also adapted for different metal oxide nanomaterials.
