“…% for furnace-cooled A1-0.1 at. % Ag also agrees well with 11.2 nQ m/at.% obtained for furnace-cooled AI-0.1 at.% Ag by Kawata and Kino (1975), who analysed the solute concentration with atomic absorption spectroscopy. Therefore, we can attribute the observed enhancement of ps to clusters in these alloys.…”

The residual electrical resistivity of dilute aluminium-silver foils with thicknesses of 30-1300 mu m has been measured. The silver concentration is 0.01-0.1 at.%, and three heat treatments are used, referred to here as furnace cooling, air quenching and quenching followed by aging. The resistivities of foils show various features consistent with the presence of Guinier-Preston (GP) zones. A strong enhancement of surface resistivity rho s (=foil resistivity-bulk resistivity) is found in these foils: rho s increases with solute concentration and becomes about 4-5 times as large as that in the solid solution and in Fuchs-Sondheimer theory. The enhanced rho s decreases to about a half upon aging for six days at 350 K after quenching from 871 K. These results strongly suggest that anisotropy in GP zone scattering enhances rho s.

“…The residual resistivity p o (4.2K) of the currently investigated AI-Si alloys is proportional to the solute concentration, indicating that the Si atoms are homogeneously distributed. The residual resistivity per atomic per cent is about 0.580 X Q cm at.%-', which is in excellent agreement with the calculated value of 0.580 x 51 cm at.%-' (Fukai 1969), while it differs from the values of 0.650 x Q cm at.%-l obtained by Kawata and Kino (1975), 0.720 X Q cm at.%-' obtained by Fickett (1971) and 0.670 X 52 cm at.%-' obtained by Takamura (1965). The probable reasons for the differences between the present and the previous values are believed to be the existing impurities in silicon and the metallurgical preparation of the samples.…”

Electrical resistivity and deviation from matthiessen's rule in polycrystalline lead-doped tin

et al. 1994

The results of measurements of the electrical resistivity, p, of lead-doped {weight concentrations: 0.001, 0.01, 0.1, and 1%) polycrystalline tin are presented. The experiments were performed using a comparative method with the aid of a tantalum thermomagnetic modulator applied as a null indicator. A nonlinear dependence of the residual resistivity on lead concentration was obtained. An anomalous character of piT) dependence was observed in the lowest-Pb concentration sample (0.001%). The deviation of the resistivity-temperature characteristics from Matthiessen's rule (DMR) was determined. The characteristics of the DMR do not show "humps" in the temperature range from 3.7 to 28 K.
