1, nanotechnology is the abbreviation of nano-material technology, which refers to the free control of atoms or molecules on the scale of (1 nm = 10-9 m), and the development of new materials or equipment on this scale.
2. The scope of nanotechnology is very broad, including various technologies, such as using a brand-new method called molecular self-assembly to manufacture semiconductor devices and developing new materials called nano-scale nanomaterials.
3. The static part of the new material and the computer stage have been applied to the processor, but it is expected that the nano-robot and disposal through this technology will be used in buildings with self-proliferation ability.
3. Nanotechnology is considered as a field that will develop greatly in 2 1 century.
There is also a debate about the future of nanotechnology. Although various new materials and equipment are expected to play a role in nanotechnology, their impact on the environment and human body has also attracted much attention.
People are also worried about the impact on the global economy and the danger that nano-machines will become uncontrollable.
6. The debate about whether it is necessary to make special regulations on nanotechnology continues.
7. Controlling materials at the nanometer level has several advantages. For example, at present, the size of transistors used in electronic circuits such as computers is about tens of nanometers, but if it can be reduced to110, computers will become smaller and necessary.
8, can inhibit the generation of electricity and heat. Similarly, it is expected that storage devices and the like will be smaller and more functional.
9. When a substance is made into several nanometers, a special phenomenon called quantum effect will appear.
10, which is used in the recent electronic equipment, is limited by electrons, and the magnitude of energy level dispersion and the distance of tunneling effect are in the nanometer range. Besides electronic materials, we also try to develop medical applications, such as drug delivery systems.
1 1, the field of nano-materials includes research and material development, which should become the unique performance of nano-materials.
Colloids and surface chemistry are carbon nanotubes, such as fullerenes, various nanoparticles and nanorods, which provide valuable materials in nanotechnology.
13, nano-materials have various uses. At present, many commercial nanotechnology are related to nanomaterials.
14, the research is applying nano-materials to medicine (nano-medicine), and solar cells made of nano-materials are also in use, competing with conventional silicon for solar cells and costs.
15. The semiconductor engineering technology developed for microprocessor manufacturing makes it possible to form the structure below 100nm, which has reached the level of nanotechnology. Giant magnetoresistance is made by hard disk atomic layer deposition (ALD), which can be said to be one of nanotechnology.
