This is an animation of
pulsed laser interval deposition of a YCuO2/BaCuO2 superlattice. The
in-situ monitoring is done by high-pressure RHEED. After an introduction of the
principle of high pressure RHEED, you will see in the inset (upper right) the
real time RHEED intensity data of the specular spot during the growth of the
two different materials and (upper left) simultaneously the HREM image obtained
from such a superlattice.
