โœฆ Synopsis


Dynamical scattering process of electrons at crystal surfaces is investigated with reflection high energy electron diffraction (RHEED). Surface captured Bragg reflections and surface waves are observed in transmission-RHEED (TRHEED) experiments. A technique, convergent beam transmission-reflection diffraction (CBTRD), through which it is possible to give a direct comparison between the scattering properties of a crystal surface and the bulk, is described. A physical picture is described to characterize the generation processes of various scattering in RHEED.
