Solids with more than one atom in the smallest unit cell exhibit two types of phonons: acoustic phonons and optical phonons. Acoustic phonons are coherent movements of atoms of the lattice out of their equilibrium positions. If the displacement is in the direction of propagation, then in some areas the atoms will be closer, in others farther apart, as in a sound wave in air (hence the name acoustic). Displacem… WebJan 7, 2024 · Dispersion curve relation describes electrical and optical propertyof solids diatomic lattices interact to each other through acoustical and optical branches,physically when k=0 there is...
