lattice wave मीनिंग इन हिंदी

From the perspective of solid state physics, Brillouin scattering is an interaction between an electromagnetic wave and one of the three above-mentioned crystalline lattice waves.
The presence of the reciprocal lattice wave vector implies a net phonon backscattering and a resistance to phonon and thermal transport resulting finite ? L, as it means that momentum is not conserved.
Gunn's research papers on solid state physics and electronics relate to microwave oscillations, lattice wave amplification, the Hall effect, quantum electronics, and applications of microwave oscillations to astrophysics.
