Reflection high energy electron diffraction (RHEED) intensity oscillat
ions were observed during molecular beam epitaxy (MBE) growth of Ge on
Si(111) surface. At 250 degrees C the oscillations continue up to 6 m
onolayers. The intensity of the reflected beam is calculated by solvin
g the one-dimensional Schrodinger equation. Monte-Carlo simulation was
used for the growth simulation in order to investigate fundamental be
haviours of reflectivity chan during the Stranski-Krastanov growth of
Ge on the Si(111) surface at 250 degrees C. (C) 1997 Elsevier Science
