Ultra-thin atomic layer thermal insulation

All modern electronic devices at workgenerate heat that adversely affects the overall operation of the gadget. Therefore, the creation of an effective system isolating some of the most active nodes in laptops, smartphones or tablets, from the rest of the electronic filling, is one of the priority tasks for developers.

Scientists from Stanford University have proposedAn original solution using a multilayer material, each of whose layers is comparable in thickness to an atom, and the total width of the material does not exceed the total diameter of 10 (ten) atoms. At the same time, the efficiency of insulation from thermal radiation is 100 times higher than that of standard glass.

The idea of ​​using multi-layer heat protectioncame to the project manager, who considered heat transfer from the point of view of broadcasting sound vibrations that are effectively damped by multilayer protection, as, for example, is achieved in ordinary fiberglass windows.

Basic requirement after high performancethermal protection to the material is the minimum thickness to maintain the compact size of the developed gadgets. Therefore, the researchers decided to use ultrathin atomically thin elements. As a result, for testing, a material consisting of 4 layers was adopted, one of which is graphene consisting of atomic carbon. The total thickness of the material is up to 10 atoms.

The main task of developers is todevelopment of an industrial method for creating an ultra-thin atomic heat insulator. It is also planned to purposefully use thermal fluctuations, by analogy with electricity.
