Techniques such as Brillouin light scattering, ultrafast laser spectroscopy, and scanning thermal microscopy are used to study the phononic band structure, phonon dispersion, and thermal transport in ...

Phonon-polaritons are a unique type of electromagnetic wave that occurs when light interacts with vibrations in a material's crystal lattice structure. These phonon-polariton waves exhibit several ...

The work 'Hyperbolic phonon-polariton electroluminescence in 2D heterostructures', led by researchers at the US Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC), could pave the ...
