Note: This classification of nanomaterials (nanostructures) is not an apparent and worthless classification. These three types of nanostructures have fundamental differences, both in terms of synthesis and production, as well as in terms of properties and applications. In general, the electrical, optical, magnetic, surface, etc. properties of these three structures are fundamentally different from each other, and of course their applications are also different.
The main basis of nanotechnology is the use of materials. Every material in space has three dimensions of length, width and height. If in materials at least one of these three dimensions is in the nanometer range, it is called a substance, a nanostructure. There is no accepted definition for the nanometer range, but a more acceptable definition is the range of one to one hundred nanometers. Nano Carbon Nano Carbon is a form of carbon nanoparticles. Using low-temperature physical peeling of natural carbon (the material used in pencil) in non-ionized water, nano carbon carbon powder is produced. This means that Nano carbon is exposed to temperatures below 650 ° C. The final material is stable at room temperature and shows no signs of flammability.
Nano carbon has many applications in nano and nanoelectronics. Carbon is one of nature's most amazing elements, found in nature in four different forms: graphite, diamond, coal, and other forms of carbon. All four of these shapes are solid, and in their structure the carbon atoms are arranged side by side in a complete and orderly manner. Carbon is one of the most important elements in nature and its many applications in human life, well confirms this point. Steel, for example, which is one of the main engineering alloys, is obtained by dissolving about two percent of carbon in iron; By changing the percentage of carbon to only a few hundredths of a percent, steels can be obtained. "Organic chemistry" is also a science that studies compounds containing "carbon" and "Hydrogen" and polymer engineering is based solely on the element carbon. Carbon is found in four different forms in nature , all of which are solid forms, and in their structure carbon atoms are arranged next to each other in a completely regular manner.
An example of carbon nanostructures
Carbon-based nanotransistors are very serious candidates to replace conventional silicon transistors. Transistors are the main electronic components that are used as amplifiers in analog circuits or electronic switches in digital circuits . And their development is the main key to nanoelectronics in the field of production and monopoly (nanochips) in the field of development of military and biological industries. Transistors and integrated circuit fabrication technology have become the most common basis for them, CMOS technology in the micro and nanoelectronics industry. This industry and technology of manufacturing integrated circuits, this advantage of nanoelectronics in reducing the size of transistors and The number of transistors used in each chip doubles. Reducing the dimensions of the transistors increases the speed and reduces the power losses.
Conclusion :
This classification of nanomaterials (nanostructures) is not an apparent and worthless classification. These three types of nanostructures have fundamental differences, both in terms of synthesis and production, as well as in terms of properties and applications. In general, the electrical, optical, magnetic, surface, etc. properties of these three structures are fundamentally different from each other, and of course their applications are also different.
