Nowadays, many technologies are disguised as high-tech "nano" technology, but in fact they are not that powerful. That is the study of very small atoms and molecules, and the creation of new equipment. It is not as developed as the application of cups, so we must be careful to distinguish and treat it with caution. The so-called nanotechnology refers to a new technology that studies the movement patterns and characteristics of electrons, atoms and molecules at a scale of 0.1 to 100 nanometers. In the process of studying the composition of matter, scientists have discovered that several or dozens of countable atoms or molecules isolated at the nanometer scale significantly exhibit many new properties, and the technology of using these properties to manufacture devices with specific functions , is called nanotechnology. Nano. The main difference between nanotechnology and microelectronics is that nanotechnology studies the control of individual atoms and molecules to achieve specific functions of the device and uses the volatility of electrons to work; while microelectronics mainly controls electrons. The group realizes its function by using the particle nature of electrons to work. The purpose of people's research and development of nanotechnology is to achieve effective control of the entire microscopic world. Nanotechnology is a comprehensive subject with strong cross-cutting characteristics, and its research content covers a wide range of modern science and technology. In 1993, the International Nanotechnology Steering Committee divided nanotechnology into six subdisciplines: nanoelectronics, nanophysics, nanochemistry, nanobiology, nanofabrication and nanometrology. Among them, nanophysics and nanochemistry are the theoretical basis of nanotechnology, and nanoelectronics is the most important content of nanotechnology.
