Abstract

It has previously been suggested, based upon multislice calculations, that electron diffraction from a surface reconstruction can be interpreted kinematically with a pseudo-kinematical condition setup for the underlying crystal. These calculations were carried out under conditions where the numerical multislice integration would not have fully converged. The intention of this note is to provide direct experimental evidence from the boron-doped Si(111)√3×√3 R30° surface that the kinematical assertion is valid.

This work was supported by the Airforce Office of Scientific Research on grant number AFOSR 86-0344 DEF. Funding for the UHV microscope was provided by the Keck Foundation, the National Science Foundation and the Airforce Office of Scientific Research, and would have been impossible without the efforts of Rob-bie Kosak.
