In actual materials the background ions forming the crystal are not fixed rigidly but vibrate. The vibration increases as the temperature is increased. To understand the properties of electrons in a ...

In this study, the researchers obtained high-quality β-MoB 2 single crystals by improving the crystal growth process, and further investigated its phonon ... layer in the lattice structure.

However, in a material, this emission process can also be accompanied by the emission of a phonon — a quantized lattice vibration ... a high-purity synthetic crystal (as in previous reports ...

Interaction between spins and the crystal lattice of a material is essential ... The researchers found a new regime of coupled magnon–phonon dynamics that allows energy exchange between these ...

Recently, phonon polaritons—coupled excitations of electromagnetic waves with atomic lattice vibrations—particularly hyperbolic phonon polaritons in thin layers of hexagonal boron nitride (h ...
