Abstract

A schematic diagram showing Cu/Ni NW based interconnects fabricated in a hybrid approach employing top-down and bottom-up methods.

Self-assembly, alignment, and patterning of metal nanowires

“…The magnetic field can be used to align MNWs along the lines of magnetic force. [60][61][62][63] This method is only applicable to NWs either made of or modified with magnetic materials, such as nickel NWs (NiNWs) and Fe 3 O 4 -modified AgNWs (Fe 3 O 4 -AgNWs). 191,192 In a magnetic field, thousands of magnetic NWs can be aligned in one step and form a head-to-tail chain.…”

“…The self-assembly strategies of MNWs, such as the coffeering effect and ice template methods, are first described to show their advantages of low cost, easy operation, and flexible controllability. 32,34,35,[45][46][47][48][49][50][51] Subsequently, we discuss the methods to realize the alignment of MNWs, including the classical Langmuir-Blodgett (LB) technique, 30,[52][53][54][55][56][57][58][59] assembly in an electric and magnetic field, [60][61][62][63][64][65][66][67][68][69][70][71][72] bubble blowing technique, 73,74 electrospinning, [75][76][77][78][79][80][81] electrohydrodynamic (EHD) jet printing, 12,[82][83][84][85] and recently developed assembly at air/solid-liquid interfaces like the Marangoni flow-assisted float assembly.…”

In-plane aligned assemblies of 1D-nanoobjects: recent approaches and applications

“…Magnetic fields can be used to induce the nanoobjects to orient like magnetized bars, and to form patterns that follow the field lines. [42][43][44][45][46][47][48][49][50] Atkinson and co-workers have investigated the alignment of ferromagnetic NWs within a magnetic field. 49 The angular distribution of the NWs deposited on the substrate from a dilute solution depended on the magnetic field strength.…”

Nanowire Genome: A Magic Toolbox for 1D Nanostructures

“…As copper is considerably inexpensive and abundant, it can dramatically reduce the cost of NWs for application in various fields, such as transparent conductive electrodes, when compared with that of Ag and Au NWs. Therefore, increasing attention has been devoted to the large scale synthesis of high‐quality Cu NWs . Early in 2005, Zeng and co‐workers developed a facile aqueous reduction route at low temperatures for the large‐scale synthesis of high‐quality ultralong Cu NWs (90–120 nm in diameter and 40–50 µm in length).…”
