Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by ...

A study published in the Journal of Micromechanics and Microengineering highlights the development of a novel energy harvesting device designed by engineers at Rensselaer Polytechnic Institute. The ...

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations ...
