k-Space introduces new RHEED simulation software
k-Space Associates Inc of Dexter, MI, USA — which was founded in 1992 and produces thin-film metrology instrumentation and software for research and manufacturing of microelectronic, optoelectronic and photovoltaic devices — has introduced kSA RHEED-Sim as its new reflection high-energy electron diffraction (RHEED) simulation software. Suitable for both researchers and students, simulation possibilities range from basic simulated RHEED patterns of common structures to complex patterns produced by reconstructions or complex surfaces, and even dynamic simulations with changing phenomena.
With kSA RHEED-Sim, users can define the crystal surface and experimental parameters. The software renders the predicted pattern based on a kinematic, single scattering electron beam diffraction model.
Highlights of kSA RHEED-Sim include:
- visualize the 3D crystal structure for predefined or generated presets;
- visualize the 2D surface structure relative to the incident electron beam, and see it update live as parameters are changed;
- define new surfaces to simulate from bulk crystal data loaded from CIF files or generated manually;
- overlay your simulation output with other RHEED image data;
- approximate the effect of surface reconstruction.
kSA RHEED-Sim is available as a standalone application or integrated with the kSA 400, which is reckoned to be the world’s leading analytical RHEED system.
