Note: Many nanowires, as their name implies, are made from organic compounds. In addition to metallic and semiconductor 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. Another nanostructure that has been studied and researched today is nanowires. A wire is generally a structure that extends in one direction (longitudinal direction) and is very limited in the other two directions . An essential feature of these structures, which have two outputs, is electrical conductivity. Electrical charge transfer occurs by applying an electric potential difference at both ends of these structures and along their length. Making wires in nanometer dimensions is very interesting both technologically and scientifically, because in nanometer dimensions, they have unusual properties. The ratio of length to diameter of nanowires is very high.
The physical properties of nanowires of organic compounds include their electrical, photoelectric and mechanical properties. Nanowires ( SiNWs) have high mobility and surface-to-volume ratios, making them easy to control using a weak electric field. These one-dimensional nanostructures are made of nanowires with a diameter in the range of nanometers and a length of more than micrometers. In the construction of nanowires from regular one-dimensional arrays with the help of different physical and chemical methods. Methods such as electron beam or lithographic methods, heavy ion irradiation, lasers, chemical and electrochemical methods such as water heat, and spontaneous aggregation methods used to make mold membranes can also be used . In the construction of one-dimensional nanostructures such as nanowires of organic compounds by electro-accumulation method, there are three general steps: first, the construction of a porous mold as a substrate and a suitable framework for the accumulation of nanowires, second, the growth of nanowires in the form of mold cavities and third The removal of the mold and the separation of the nanowires from it. The properties of the nanowires directly depend on the characteristics of the mold surface such as the size distribution of the holes, the density of the holes and the superiority of the surface of the nanopores. To control the properties of nanowires of organic compounds must be taken into account the parameters that affect the formation and optimization of pore diameter and mold thickness.
Conclusion :
These types of nanowires, as their name implies, are made from organic compounds. In addition to metallic and semiconductor materials, it is also possible to make nanowires from organic materials.
