SpletAdditionally, some previous studies revealed that sometimes Wiedemann-Franz law would be violated,8-10 thus leading to unreal values of L. Here in this work, we first carried out L calculations from the reduced Fermi energy (η) according to Equation S8 and obtained considerably large L value, ~2.42×10-8 V2K-2 at RT and ~1.95×10-8 V2K-2 at ...

In many high purity metals both the electrical and thermal conductivities rise as temperature is decreased. Prikaži več In physics, the Wiedemann–Franz law states that the ratio of the electronic contribution of the thermal conductivity (κ) to the electrical conductivity (σ) of a metal is proportional to the temperature (T). Prikaži več Qualitatively, this relationship is based upon the fact that the heat and electrical transport both involve the free electrons in the metal. The mathematical expression of the law can be derived as following. Electrical conduction of … Prikaži več Experiments have shown that the value of L, while roughly constant, is not exactly the same for all materials.
