. Nanometer, is a unit of length, the symbol for nm. 1 nanometer = 1 millimicron = 10 meters (both one billionth of a meter), about the length of 10 atoms. Assuming that the diameter of a hair is 0.05 millimeters, it is radially dissected into 50,000 roots on average, and the thickness of each root is about 1 nanometer.
. 1, the meaning of nanotechnology
. The so-called nanotechnology, refers to the scale of 0.1 ~ 100 nanometers, the study of electrons, atoms and molecules within the laws of motion and characteristics of a new technology. Scientists in the study of the composition of matter in the process, found in the nanometer scale isolated a few, dozens of countable atoms or molecules, significantly show many new characteristics, and the use of these characteristics of the manufacture of equipment with specific functions of the technology, known as nanotechnology.
. The main difference between nanotechnology and microelectronics technology is: nanotechnology research is to control individual atoms, molecules to achieve specific functions of the device, is the use of the volatility of electrons to work; and microelectronics technology is mainly through the control of the electronic group to achieve its function, is the use of electrons to work on the particle nature. The purpose of people's research and development of nanotechnology is to achieve effective control of the entire microcosm.
. Nanotechnology is a highly cross-cutting and comprehensive discipline, and the research involves a wide range of modern science and technology.In 1993, the International Nanotechnology Steering Committee divided nanotechnology into six sub-disciplines, including nanoelectronics, nanophysics, nanochemistry, nanobiology, nanofabrication and nanometrology. Among them, nanophysics and nanochemistry are the theoretical basis of nanotechnology, while nanoelectronics is the most important element of nanotechnology.
. 2, the characteristics of nanoelectronic devices
. The performance of electronic devices made with nanotechnology is greatly superior to that of traditional electronic devices:
. Fast working speed, nanoelectronic devices work 1000 times faster than silicon devices, which can greatly improve product performance. Low power consumption, nano-electronic devices, power consumption is only 1/1000 of silicon devices. large information storage, in a less than palm-sized 5-inch CD-ROM, at least 30 Beijing Library can store all the books. Small size, light weight, can make all kinds of electronic products volume and weight greatly reduced.
