(Nanowerk News) Electrons carry electrical energy, while vibrational energy is carried by phonons. Understanding how they interact with each other in certain materials, like in a sandwich of two ...

Researchers have captured the first direct, momentum-resolved evidence that certain lattice vibrations carry measurable ...

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

This makes phonon-polaritons ideal for high-tech applications like sub-wavelength imaging, molecular sensors, and heat management within electronics. However, research on phonon-polariton waves has ...
