Note: In electronics, the topic of nano-axis (nano memories; nano chips and nano fast chips and nano electronics) is less weighty and more efficient.
Nanotechnology, knowledge, engineering and technology at the nanoscale or in other words and the study of the use of very small objects and their use in all fields of science such as chemistry, biology, electronics; Materials science and engineering. The study of the behavior of light based on the interactions of science and engineering of optical materials is done at the wavelength and wavelength scales, in which natural or chemical projects of natural materials of nanostructure or nanotechnology at the nanometer and synthetic scale using optical These include silicon-based semiconductors (where nanophotonics improve speed and performance) associated with specific technologies such as optical engineering, electrical engineering and nanotechnology.
In general, nanophotonics behave light at the nanometer scale and interact at the nanometer scale with light. Photons are unique and different from other particles due to their properties. Because photons have the properties of waves as well as the properties of natural particles. This means that it can be refracted by the lens while interfering with other waves while being simultaneously analyzed as a particle of matter. A photon is a particle that has energy and motion. However, it has no mass or electrical charge. Photons are elementary particles and are known as quantum electromagnetic nutrients. This type of particle can not be divided like other particles such as except components. Properties such as strength, flexibility, electrical conductivity, magnetic properties, color, reactivity and so on. Start changing the properties of the material by shrinking it Above all, it depends on the type of material and the desired property. For example, as the dimensions of a material shrink, some of the mechanical properties of materials, such as strength , generally improve. This increase in strength does not occur only in the range of a few nanometers, and the strength of materials of several tens or even hundreds of nanometers may be much greater than that of large-scale bulk material. On the other hand, changes in some properties, such as color and magnetic properties, may occur in dimensions of only a few nanometers. In addition to these two, the state of the energy levels of the electrons around each atom, as well as the number of electrons in its last layer , also determine the properties of that atom or substance. This property can play a decisive role in the mechanism by which the substance combines its chemical properties. for example The properties of a metal ion differ from those of the metal atom. So far, the role of the three factors of atomic number, mass number and electron arrangement of matter in determining the properties of electrons in the nanostructure of matter is influential. The macroscopic properties of a material, such as melting point, boiling point, and electrical conductivity, are determined by studying a sample sufficient to measure under normal nanoparticle conditions. This is not true for all materials, when the size of the material is reduced to nanometer dimensions, completely different behaviors and properties may be observed for the same material in large dimensions.If a material with a slit structure of nanoelectronic devices with a scale of several tens of meters is reduced to millimeter dimensions, there will be no change in its melting point, color and magnetic properties, but this change when the material is reduced in size. It is seen in nanometers and the number of surface atoms in materials with scales larger than nanometers is very small, but entering the world of nanometers, the amount of these atoms is much higher than the total atoms of matter.
Conclusion :
The study of the behavior of light based on the interactions of science and engineering of optical materials is done at wavelength and wavelength scales, in which natural or chemical projects of natural materials of nanostructure or nanotechnology at the nanometer and synthetic scale using optical These include silicon-based semiconductors (where nanophotonics improve speed and performance) associated with specific technologies such as optical engineering, electrical engineering and nanotechnology.
