Created a heat shield for electronics with a thickness of only 10 atoms

Atomic Scale Heat Shield For Electronics Just 10 Atoms Thick -New Discovery

A heat-shielding coating of several layers of atomically thin materials, stacked in succession, provides the same insulation as a sheet of glass, which is 100 times thicker. The opening will make electronic devices more compact and safer.

The electronics generate an inaudible form of high frequency sound that we perceive as 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 cause devices to malfunction or even explode the battery. To avoid such problems, engineers usually use glass, plastic, or layers of air as insulation..

Thinking of heat as a form of sound, Stanford University researchers borrowed some of the physics principles used in recording studios and laminated windows to develop the nanoscale heat shield. .

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

To make nanoscale heat shields practical, researchers it will still be necessary to develop a special technique for applying atomic layers of material to electronic components during their production. However, beyond its original purpose, scientists hope to one day use thin insulators to control vibrational energy within materials in the same way as electricity and light..

Earlier, we also reported on the invention of thin polymer films that conduct heat better than many metals, which can be used for its dispersion and removal.
