Note: The advantages of Oligophenylene vanillin nanowires in the use and development of sensor operating systems are due to the well-known properties of silicon and its favorable manufacturing processes. Among the physical properties of these nanowires, we can mention their electrical, photoelectric and mechanical properties.
Oligophenylene vanillin nanowires are one of the best examples of semiconductor nanostructures that can be made as a single crystal with a diameter of 9 to 0 nm. "Oligophenylene vinylene" nanowires 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 a micrometer. It has been done in the manufacture of nanowires through regular one-dimensional arrays with the help of different physical and chemical methods.
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 by the electro-accumulation method, there are three general steps: firstly, the creation of a porous template as a suitable substrate and framework for the accumulation of nanowires, secondly, the growth of nanowires in line with the cavities of the template, and thirdly, removal The mold and the separation of nanowires are from it. The properties of nanowires are directly dependent on the surface characteristics of the mold 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 properties of Oligophenylene vanillin nanowires It should be the parameters that are effective in the formation and optimization of the diameter of the holes and the thickness of the mold.
Conclusion :
Oligophenylene vanillin nanowires such as cobalt, nickel, iron and alloys can be made by electroaccumulation and spontaneous accumulation on an anodic aluminum oxide mold, and the magnetic properties of cobalt nanowire arrays such as coercive force, saturation electromagnetism and magnetization The rest depends on the configuration of the nanowires and the diameter of the nanowires. This characteristic of "Oligophenylene vanillin" nanowires can be easily controlled by changing the influencing factors in mold making, such as the potential of the oxidation process and pH. He pointed out applications in chemical nano sensors, logical nano tools and other nano electronic and nano optical tools.
