A heat shielding screen for electronics with a thickness of only 10 atoms 2 октября, 2021

The heat-shielding coating of several layers of atomically thin materials, isolated alternately, provides the same isolation as a glass sheet, which is 100 times thicker. Opening will make electronic devices more compact and secure.

When the electronics is operated, the unabled form of high-frequency sound, which we feel both warmth. This is due to the collision of charged particles with the atoms of the materials through which they pass.

In addition to irritation, this energy can lead to malfunctions in the operation of devices or even to the explosion of the battery. In order to avoid such problems, engineers typically use glass, plastic or air layers as insulation.

Reflecting on warmth as a sound form, when developing a nanoscale heat shield, researchers from Stanford University borrowed some physical principles used in recording studios and multilayer windows.

Instead of thick glass mass, the command used a graphene layer and three other sheet material with a thickness of 3 atom to create a four-layer insulator in just 10 atoms. Despite its subtlety, it is effective because when passing through each subsequent layer, thermal fluctuations of the atom weaken and lose most of their energy.

In order to make nanoscale heat shields practical, researchers still need to develop a special technique for applying atomic layers of material into electronic components in the process of their production. However, in addition to initial destination, scientists hope one day to use thin insulators to control the vibration energy inside the materials as well as electricity and light.
