Thermoelectric Power and Resistivity in a Metallic Glass

Several theories have attempted to explain the anomalous temperature dependence of the resistivity in metallic glasses including a generalized Ziman theory, a model based on Mott s-d scattering, and a model based on a Kondo or tunneling mechanism. The thermoelectric power as well as the resistivity of a glass has been measured up to the crystallization temperature and was linear over the entire region. This behavior is only consistent with the Ziman theory.
