Orientational epitaxy of the hexagonally reconstructed Pt(001) surface

X-ray scattering studies of the orientational epitaxy displayed by the hexagonally reconstructed Pt(001) surface are described. At 1685K, the reconstructed surface layer undergoes a continuous rotational transformation with respect to the underlying bulk and exhibits mean-field behavior. A second, d...

description X-ray scattering studies of the orientational epitaxy displayed by the hexagonally reconstructed Pt(001) surface are described. At 1685K, the reconstructed surface layer undergoes a continuous rotational transformation with respect to the underlying bulk and exhibits mean-field behavior. A second, discontinuous rotational transformation is observed at 1580K. These results are inconsistent with the predictions of current theories and lead to a mean-field description of rotational transformations.
