(General Physics) a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kel...
Three distinct regions were observed in the temperature-dependent resistivity ( ρ - T ) graph. An upturn in the ρ - T curve was observed below 100 K, which was enhanced with decreasing grain size. This enhancement was investigated, and the analysis suggests that elect...
The expression for resistivity can be written in the following form: 1 = 10 exp (EA/kBT ) , (4) where T is the absolute temperature, 10 the value of resistivity at infinite temperature, EA the activation energy and kB the Boltzmann's constant, i.e., for the bandgap model the graph ...
