rheed++: A C++ framework to simulation of RHEED intensity oscillations during the growth of thin epitaxial films

摘要

A time-efficient, compact and flexible computer model has been developed for calculations of RHEED intensity oscillations during the growth of thin epitaxial films. The main functionality of the model is its ability to perform dynamical calculations of amplitude of the RHEED specular beam intensity oscillations as a function of growth time using the scattering potential for heteroepitaxial structures, accounting for the possible occurrence of diffuse scattering through the layer parallel to the surface. The existence of a large number of user-definable parameters make the presented model highly versatile. To validate the model, a calculated plot of the RHEED oscillation has been compared with experimental data taken from the literature. The model does not require linking to any of the existing numerical library routines.
