A method of calculating reflection high-energy electron diffraction intensities is developed within the framework of two-dimensional Bloch-wave approach In the course of computations only wave-field-related quantities are employed (rather than transfer or scattering matrices) The intensities of reflected beams are calculated iteratively The very good convergence of the method is demonstrated for Pt(111) For scattering systems with a large number of diffracted beams (exceeding 100\char21{}500) this iterative method is potentially faster than traditional direct methods More importantly, a number of possible approximations can be easily derived on the basis of the iteration sequence introducedread more

Investigation of iterative RHEED calculations
TL;DR: In this paper, the convergence properties of iterative RHEED calculations are dependent on diffraction conditions and two approaches for overcoming them are reported, one involves shifting the eigenvalues of the iteration operator and modifying the Green's function used to construct it, the other is a biconjugate gradient technique.

Incommensurability imposed by the low-temperature phase transition at the (001) surface of SrTiO3
N.V. Krainyukova,V.V. Butskii +1 more
TL;DR: In this paper, the reflection high-energy electron diffraction (RHEED) study of the SrTiO3 surface structure in the temperature region from 6 to 300 K shows the anomalous growth of the surface lattice parameters under the temperature decrease, ascribed to the specific character of the low-temperature phase transition connected with the rotation of the metal-centered oxygen octahedra around the normal to the (0,0,1) surface.
