Expérimental Description
Phonons are the quanta of vibrations in a crystalline lattice. When a solid-state system is subjected to an external excitation, its relaxation to thermodynamic equilibrium generates phonons, which propagate and encounter scattering events at the origin of heat diffusion. The phonon relaxation dynamics is thus mostly non-radiative, and phonons are usually considered only as a dissipative reservoir. This project deals with the demonstration of light generation by phonons.
