“Priority 2030”: Moscow Poly Obtained Samples of Thin-Film Materials for Nano Electronics
Moscow Poly scientists obtained samples of defect-proof thin-film materials used for nanoelectronic devices. The samples obtained have unique physical-chemical exploitation characteristics necessary for creating energy-efficient and ecologically friendly devices for car- and rocket engineering, as reported by the “Kommemrsant” news.
“Our project is intended for 3 years. In the course of the research, we acquired lab samples of thin-filmed materials from several combinations, studies their structure and partially identified their properties”, – shared the project head Alexander Kazak – “These materials can be potentially used in nonlinear optics as their possess the properties that can be used as laser radiance reducers. It might be beneficial to pilots` eyes, aircraft devices and spacecrafts since the laser radiance may be dangerous to pilots` health and eye sight.”
The diversity of methods of precipation into the solid underbed with the desired structural and optical parameters. In their research, the Russian scientists use the method of obtaining materials that is based on floating selection transfer from the surface of air/water phase interface to the underbed. This allows to achieve a higher order of the molecular layers than in other methods.
First, the scientists obtain a solution of organic combination in a highly volatile solution of a certain concentration. At that, the combinations themselves are not water or mineral soluble. After that, taking the consideration the molecules geometric parameters, a certain amount of solution from an organic combination is applied on the water surface with the help of special batchers or syringes. The amount applied is equal to tens and hundreds of microliters. In 15-20 minutes after the application of the solution onto the water surface the dissolvent should evaporate so that only organic combination is only left.
The next step is forming the film with the help of special moving barriers and control of surface pressure When the necessary film structure is achieved, it gets transferred onto the solid underbed in the form of various materials such as silicium or glass with electrodes. If it`s the optical properties that are studied, the quartz glass should be used as the underbed.
The project has been implemented in the framework of the “Priority 2030” program national project under the “Science and Universities” national project.
