Implication

Experimental study reveals temperature-independent isotope effects during copper self-diffusion, indicating minimal divacancy contributions to atomic transport.

Key Points

Determine the isotope effect and quantify the role of divacancies during self-diffusion in copper single crystals at elevated temperatures.
Measured simultaneous diffusion of radioisotopes 64Cu and 67Cu in copper single crystals across temperatures ranging from 890 to 1061 °C.
Calculated the diffusion coefficient of 67Cu in copper single crystals between 700 and 1060 °C.
The isotope effect parameter fΔK was 0.684 ± 0.014 across the tested range.
The isotope effect was independent of temperature within experimental error, demonstrating that divacancies make only a minor contribution to copper self-diffusion.
