Note: Many nanowires, as their name suggests, are obtained from organic compounds. In addition to metallic and semi-conducting materials, it is also possible to make nanowires from organic materials. 

The characteristics of these wires (such as conductivity, resistance, and thermal conductivity) depend on the structure of the monomer and its arrangement. Nanowires are another nanostructure that  has received many studies and researches.  Generally, the wire is said to be a structure that is extended in one direction (longitudinal direction) and  is very limited in the other two directions. A basic feature of these structures that have two outputs is electrical conductivity. By applying the  electric potential difference at the two ends of these structures and along their length, electric charge transfer occurs.

Making wires in nanometer dimensions is very interesting both from a technological and scientific point of view, because in nanometer dimensions  they show unusual properties. The ratio of length to diameter of nanowires is very high.

From the physical properties of nanowires of  organic compounds,  we can mention their electrical, photoelectric and mechanical properties. Nanowires ( SiNWs) have high mobility and surface-to-volume ratio, which makes them easy to control using a weak electric field.  These one-dimensional nanostructures  are created from nanowires with a diameter in the range of nanometers and a length of more than micrometers. It has been done using different physical and chemical methods in making nanowires through regular one-dimensional arrays  . Methods such as  the use of electron beam or lithography method, heavy ion irradiation, laser, chemical and electrochemical methods  such as water heat and spontaneous assembly methods used to make the membranes of molds can also be used  .

In the manufacturing of one-dimensional nanostructures such as nanowires of  organic compounds  by electro-accumulation method, there are three general steps: firstly, the creation of a porous mold as a suitable substrate and framework for the accumulation of nanowires, secondly, the growth of nanowires in line with the holes of the mold and thirdly. removing the template and separating the nanowires from it. The properties of the nanowires are directly dependent on the features of the template surface, such as the size distribution of the holes, the density of the holes, and the superiority of the surface of the nanoholes. To control the characteristics of nanowires of  organic compounds,  the parameters that are effective in the formation and optimization of the diameter of the holes and the thickness of the mold should be considered.


Conclusion: 

This type of nanowires, as their name suggests, are obtained from organic compounds. In addition to metallic and semi-conducting materials, it is also possible to make nanowires from organic materials.
