- Summary
- Each interface contained a layer of the appropriate tracer and an inert radioactive Hf/sup 181/O/sub 2/ marker. During the temperature gradient anneal, the maximum of the tracer profile at the hot interface shifted with respect to the Hf/sup 181/O/sub 2/ marker. Heat of transport of Au/sup 195/ in gold was found to be 0.80 +- 0.27 eV. This value supports Huntington's theory. The heat of transport of Ni/sup 59/ in nickel was estimated to be 1.3 +- 7.2 eV. The experimentally determined value of the Sb/sup 125/ heat of transport in gold was -2.02 +- 0.23 eV. This large negative number indicates that the charge carrier-impurity ion interaction is the dominant driving force for Sb/sup 125/ impurity thermomigration in gold. This value compares favorably with the theoretical value for the heat carrier-impurity ion interaction of Q* = -0.5 eV for antimony thermomigration in silver.
