Abstract

The reactions of copper and amorphous silicon were studied by in-situ transmission electron microscopy up to 500 °C. Only the Cu 76 Si 24 -η phase and the Cu 82 Si 18 -δ phase formed at this temperature. The crystal structure of the dominating Cu 76 Si 24 changed, by the elapsed time after heating. The Cu–Si ordering resulted in different supercells, built up by topologically identical subcells with different site occupancies and arrangement. Two modulated crystal structures were solved based on diffraction data and HRTEM images.
