Lithography technology draws silver nanostructures for the first time

in order to obtain fine structure patterns on the surface of materials, the best choice is to use electron microscope scanning technology and use electron beam to conduct complex lithography on its surface. This technology has been applied to the fabrication of nanostructures of platinum, gold, copper and many other metal materials, but it has not been successfully applied to silver materials. Silver has a wide application prospect in the field of electronic industry. Germany has concentrated its efforts on the development of new aluminum based materials and high-end equipment manufacturing. New aluminum alloy materials, linhelmz materials and energy research center, in cooperation with the federal materials testing and Research Institute, has completed lithography nanostructures on the bottom of silver materials for the first time, opening up a new way for optical computer data processing and new electronic device manufacturing in the future. The results were published in the Journal of Applied Materials and interfaces of the American Chemical Society

this time, the research team successfully used photolithography to eliminate the procedure of measuring the opening displacement at the root of the crack Nanostructured crystals were fabricated on silver materials. The biggest difficulty in this experiment is to find suitable silver compounds and develop injection components for electron beams. Because the chemical activity of typical silver compounds is very strong and it is difficult to vaporize, even when the injection part is heated and reacts with the container wall, the channel from the container to the tip of the injection part is often blocked when the test temperature is reduced, so it is particularly difficult to meet the requirements of lithography technology

physicist Dr. hoflich said that the silver dimethyl compound they selected is very stable and only decomposes at the focus of the electron beam. The principle of silver material lithography technology polar 2, which is still in the stage of engineering development, is similar to that of other material lithography technologies. In this mode, the tip of the machine injects a small amount of lead material, usually organometallic compounds, close to the surface of the sample. The electron beam irradiates the surface of the sample, decomposes the material molecules and nonvolatile residues on the surface, and fixes them at a certain position of the sample. Like a pen, the electron beam travels upstream of the bottom layer of the material to draw the desired structure. This technology is also suitable for drawing three-dimensional structural drawings on many underlying materials

the newly developed silver nanostructure material has extraordinary optical properties. Visible light can control the vibration of free electrons in the silver structure, that is, the formation of so-called plasma elements, which are displayed by dense light beams. Through the intensity and color of light, the relevant information on the structure surface can be read. With the help of Raman spectroscopy, this effect can also be used as a fingerprint to verify specific molecules

silver nanostructures have considerable application potential in the field of electronics and information technology, and can be used as basic materials for pure optical data processing, but to be applied in practice, it is necessary to further refine the lithography process of silver nanostructures
