N. Chandrasekhar et Dg. Schlom, EVIDENCE FOR SURFACE MELTING DURING THE GROWTH OF HIGH T-C THIN-FILMS, Physica. C, Superconductivity, 235, 1994, pp. 697-698
We present reflection high energy electron diffraction (RHEED) spot pr
ofile analyses, which show anomalous broadening over very short time s
cales. Our data can only be interpreted in terms of surface melting. T
he conclusions are consistent with the thermodynamic phase diagrams an
d with the vapor-liquid-solid (VLS) mechanism of crystal growth.
