Lithographically patterned nanowire electrodeposition

A related electrochemical approach to nanoelectrode fabrication was previously demonstrated by Peimer s group. In this case a nanotrench electrode was instead used as a template for the electrodeposition of metal nanowire electrodes in a method referred to as lithographically patterned nanowire electrodeposition (LPNE). Simple photolithography was used to define a sacrificial nickel or silver nanoband electrode sandwiched between...

Besides the aforementioned templates, many other research groups have developed their own template-based electrochemical synthesis techniques. For example, photolithography methods such as the lithographically patterned nanoscale electrodeposition (LPNE) method developed by Penner are excellent ways to produce nanostructures with controllable dimensions. - With this process, the Penner group has been able to produce nanowires with length scales in the macroscale while still maintaining precise control over the nanowires height and width with resolutions in the tens of nanometers." ...
