A robust solution for RHEED
Y. Ma,Laurence D. Marks +1 more
TL;DR: In this paper, a new method of solving the reflection diffraction problem using a stabilized edge in a multislice-type calculation is described, which is a very robust solution and for one surface raises an important issue concerning the boundary match in the Bloch-wave approach.

Abstract: A new method of solving the reflection diffraction problem using a stabilized edge in a multislice-type calculation is described Results that compare it with Bloch-wave calculations show that it is a very robust solution and for one surface raises an important issue concerning the boundary match in the Bloch-wave approach It is shown that the standard boundary match used is often invalid for reflection problems and may also be questionable for transmission problems although here the effects will be smaller The correct boundary match on a surface which need not be flat is described

Quantitative analyses of RHEED patterns from MBE grown GaAs(001)-2 × 4 surfaces
TL;DR: In this article, a multislice formalism of Cowley and Moodie [Acta Crystallogr. 10 (1957) 609] with a recently developed edge patching method has been applied to quantitative analyses of RHEED patterns from MBE grown GaAs(001)−2 × 4 surfaces.

Contrast and resolution in REM, SEM and SAM
John M. Cowley,Jingyue Liu +1 more
TL;DR: Reflection electron microscopy (REM) in fixed beam and scanning modes, secondary EM and scanning Auger EM are related in that they provide nanometer-scale resolution of surfaces in moderate or ultra-high vacuum using incident electron beams having energies of the order of 100 keV as discussed by the authors.

TL;DR: The multislice formalism of Cowley and Moodie [Acta Crystallogr. 10 (1957) 609] with a recently developed edge-patching method has been applied to the analysis of an experimental RHEED (reflection high energy electron diffraction) pattern from the Si(111)-7 × 7 surface as mentioned in this paper.

Developments in the dynamical theory of high energy electron reflection.
Y. Ma,Laurence D. Marks +1 more
TL;DR: A stationary dynamical solution for an arbitrary surface for HEER has not been obtained yet and the usefulness of HeER has been widely recognized and demonstrated.
