ABSTRACTTo make Bi2Sr2CaCu2O8 superconducting films with top insulating SrTiO3, we use the molecular beam epitaxy technique (MBE) with in situ monitoring by reflection high-energy electron diffraction (RHEED). A new (RHEED)image enhancing technique, difference reflection high-energy electron diffraction (DRHEED) gave striking information on the growth process of each layer in the Bi:2212 compound as well as the rough and flat transition occurring during co-evaporated deposition of SrTi03.

In recent years there has been a trend in the structure determination of reconstructed surfaces to use high energy electron diffraction techniques, and to employ a kinematic approximation in analyzing the intensities of surface superlattice reflections. Experimentally this is motivated by the great success of the determination of the dimer adatom stacking fault (DAS) structure of the Si(111) 7 × 7 reconstructed surface.While in the case of transmission electron diffraction (TED) the validity of the kinematic approximation has been examined by using multislice calculations for Si and certain incident beam directions, far less has been done in the reflection high energy electron diffraction (RHEED) case. In this paper we aim to provide a thorough Bloch wave analysis of the various diffraction processes involved, and to set criteria on the validity for the kinematic analysis of the intensities of the surface superlattice reflections.The validity of the kinematic analysis, being common to both the TED and RHEED case, relies primarily on two underlying observations, namely (l)the surface superlattice scattering in the selvedge is kinematically dominating, and (2)the superlattice diffracted beams are uncoupled from the fundamental diffracted beams within the bulk.
