Nano Wires / Nano Rods

Copper nanowires are promising material and essential component of the nanoelectronic devices. Copper’s interconnects are downscaled to the nanometer size. Also, the copper nanowires would be usable in the future. The copper nanowires' electrical properties behave differently because the mean-free path is a few tens of nm and the electron wavelength is only a fraction of nm, comparable to the size of an atom.

Copper nanowire as a promising material in transparent conducting materials. These nanowires also show optoelectronic properties. Cu NW films have an advantage that these can achieve high optical transmittance with high electric conductivity. Copper nanowires (CuNWs) are attracting attention owing to some properties, for instance, preponderant electric conductivity, optoelectronic and mechanical properties, high electrocatalytic efficiency, and large abundance.

These nanowires provide a supreme platform to study the dependence of electrical and thermal transport. These nanowires also provide the mechanical properties on dimensionality and size reduction. To achieve high-performance Copper nanowire, it is of great importance to precisely control the dimension and structure of CuNWs due to its tendency to oxidize and aggregate and mechanical flexibility. Therefore, they have potential applications in distinct optoelectronic devices such as touchscreens, cells, OLEDs, solar and sensors.

For sensor applications, Copper nanowire have been widely examined in the development of electrochemical biosensors. Because the Cu nanowires are efficient in electron transfer and good mechanical strength. Cu NWs as a transparent conductor has utilized a resistive-type touchscreen device for touchscreen applications. In the future, there will be enormous opportunities for fabricating new designs using Cu NW-based involving flexible displays and curved surfaces.
