WebPhonon Drag If a material is very pure, and free from defects, it is called “intrinsic.” The thermopower of an intrinsic material always shows phonon drag at low temperatures. This phenomena happens in all dimensions. A complete theory was derived by Bailyn. It is complicated and will not be reproduced here. In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of interacting particles. Phonons can be thought of as quantized sound waves, similar to phot…
