Many investigations have been conducted to measure and understand the superlinear increase in threshold current as temperature is increased. The measurements made with pulsed L-I produce the same results, and a theoretical investigation into the possible processes for the superlinear relation will be ...

The resistivity of various liquid transition metals as a function of temperature (p(T)) has been measured by a number of groups and typically r = (ρ/T)p/ρ104K1. In this paper we present a compilation of data and we show how this kind of value may be obtained as a result of ...
Phonon-dislocation scattering and the phonon-drag contribution to the electrical resistivity of the alkali metals A calculation is presented of the temperature dependence of the electron-phonon scattering contribution to the electrical resistivity of the alkali metals ...

Since for most metals the resistance becomes largely independent of temperature below 4° K., this region (between 4° and 20° K.) is crucial for determining the law of resistance variation with temperature. We have now modified a previously described helium cryostatworking on the Simon ...
As an example of calculating a volume's resistance, consider the drawing to the left. Assume 12 AWG copper wire with a resistivity (from the table) of1.72x10-6Ω·cm, a cross-sectional area (A) of 0.03309 cm2, and a length of 1 meter. Per the given formula, its resistance is:...
The Temperature Dependence of the Resistivity and Thermopower in Some Polyvalent Liquid Metalsdoi:10.1080/00319107108083817Calculations of the temperature dependence of the resistivity and thermopower of liquid indium, cadmium, thallium, lead and mercury are presented. The values of the thermopower are in ...
The diagram above shows that above about 100K, the resistivity of a metal increases linearly with temperature even though the Drude model suggests it should increase according to T12. Drude model is even worse at explaining the low-temperature resistivities of very pure forms of metals. The resi...
An analysis is presented of the effect of electron-dislocation scattering on the temperature-dependent part of the electrical resistivity of the noble metals at low temperatures. The basic idea is that for any given sample, the degree to which the relaxation time varies over the Fermi surface is...
The features of this curve at high, intermediate, and low temperatures are interpreted in terms of a simplified model for an anisotropic metal. The model predicts that the a-versus-T curve for all electrically anisotropic metals with anisotropy aas T-->∞ will exhibit a maximum a=aat ...
