In the past few years, the theory has been confirmed surface phonon polaritons can increase the thermal capacity from a polar material such as silicon dioxide nanomaterials.

Polariton is a quasi-particle quantum, electromagnetic waves and electrical / tape made strong coupling Dipole. In a particular surface phonon polaritons, the electromagnetic coupling in the material to become some kind of atomic vibration frequency and polarization directions, known optical phonon.

When the material size of less than 100 nanometers, the surface properties of the material beyond the body to become the dominant characteristic of the thermal phonon coupling can with the help of electromagnetic waves, the tightly stacked between the base of the bed particles flow.

Is silicon dioxide a compound?

Yes silicon dioxide is a compound. It is also known as silica and is an oxide of silicon with a chemical formula of SiO2. It has been known for its hardness throughout history and Silica is most commonly found in the form sand and quartz, Silica is the most abundant mineral in the Earth's crust.

Because the test too difficult, the researchers had not measure heat flow surface phonon excimer, but it has been observed that appear wave propagation when light strikes the surface of a nanostructured material, which means potential applications in the field of heat dissipation.
