Cheating the diffraction limit: electrodeposited nanowires patterned by photolithography

The diffraction limit, d approximately lambda/2, constrains the resolution with which structures may be produced using photolithography. Practical limits for d are in the 100 nm range. To circumvent this limit, photolithography can be used to fabricate a sacrificial electrode that is then used to initiate and propagate the growth by electrodeposition of a nanowire. We have described a version of this strategy in which the sacrificial electrode delimits one edge of the nascent nanowire, and a microfabricated "ceiling" constrains its height during growth. The width of the nanowire is determined by the electrochemical deposition parameters (deposition time, applied potential, and solution composition). Using this method, called lithographically patterned nanowire electrodeposition (LPNE), nanowires with minimum dimensions of 11 nm (w) x 5 nm (h) have been obtained. The lengths of these nanowires can be wafer-scale. LPNE has been used to synthesize nanowires composed of bismuth, gold, silver, palladium, platinum, and lead telluride.

“…Au can be easily produced in nanoparticle form by the chemical [5,6] or photochemical [7,8] reduction of Au salts; however, the preparation of one-dimensional nanostructures is a challenging task, especially without using templates or surfactants [9][10][11].…”

A novel method for preparing vertically grown single-crystalline gold nanowires

et al. 2008

A surfactant-free, template-less and seed-less method, namely the thermal-assisted photoreduction (TAP) process, has been developed to synthesize vertically grown Au nanowires (30-80 nm in diameter and about 2 µm in length) on the surface of thin film titanium dioxide (TiO(2)), which is locally excited by blackbody radiation. The Au nanowires thus produced are single-crystalline with a preferred [Formula: see text] growth direction. The electrical behavior investigated using a nanomanipulation device indicates that the Au nanowires possess an excellent electrical resistivity of about 3.49 × 10(-8) Ω m.

“…Other methods have utilized different techniques to create templates for nanostructures. Jorritsma et al fabricated a large array of gold nanowires by using a V-grooved InP substrate made by holographic laser interference lithography. Au was evaporated on this substrate to form a Au-nanowire matrix.…”

Fabrication of Nanostructures by Hydroxylamine Seeding of Gold Nanoparticle Templates

et al. 2001

Hydroxylamine-seeding of colloidal gold particles has been used to fabricate gold nanostructures on a SiO2 substrate. Gold nanoparticles (15 nm diameter) were randomly deposited on a SiO2 surface that had been modified with aminopropyltrimethoxysilane (APTS). The nanoparticles were then manipulated using a scanning force microscope (SFM) tip to produce 1-D templates for gold deposition. We demonstrate the utility of this approach by fabricating a gold nanowire by using 13 nanoparticles as a template. The junction between joined (coated) particles was examined by mechanical manipulation, and homogeneous deposition was shown to form stable structures. This approach was also used to fabricate nanostructures in a small gap between two gold electrodes. Particles were pushed into the gap, and then gold deposition was used to "connect" the particles and electrodes. Although the particular structure tested was not electrically connected to the electrode, we suggest that this approach will be useful in tackling the difficult problems associated with electrically connecting nano-to microscale structures.
