BlochGrüneisenmodellen
The BlochGrüneisen model is a theoretical framework used in solid-state physics to describe the thermal properties of metals, particularly their electrical resistivity at low temperatures. It was developed by Felix Bloch and later refined by Edgar Grüneisen. The model accounts for the scattering of conduction electrons by lattice vibrations, also known as phonons.
At low temperatures, the dominant contribution to electrical resistivity in metals comes from electron-phonon interactions. The
A key feature of the BlochGrüneisen model is its prediction of the temperature dependence of resistivity. At
The model provides a foundation for understanding why electrical resistance in pure metals typically decreases significantly
