WebAscii-phonons is a visualisation code which uses Blender (an open-source 3D graphics package) to generate animated GIFs and static arrow diagrams of phonon eigenmodes. These may be rendered at publication quality. WebPhonon scattering by phonons is caused by anharmonic effects. One phonon divides into two, or two combine into one. The rate of this process increases with temperature, since the number of phonons in the system increases. At high temperature, where anharmonic effects are important, the energy dissipation path of a material in an electric field is:
