... Dispersion curves for the acoustic and optical phonon branches in a typical crystal with a lattice constant of a. The dispersion of the photon modes is shown by the dotted line. At small wave vectors the slope of the acoustic branch is equal to vs, the velocity of sound, while the optical modes are ...

... Lattice scattering results from thermal vibrations of the lattice atoms at any temperature above zero. These vibrations disturb the lattice periodic potential and allow energy to be transferred between the carriers and the lattice. Since lattice vibration increases with increasing temperature, latt ...
