⇒ geometric simulations of complex surface structures

⇒ calibration and correction of LEED pattern for high precision analysis

⇒ numerical fitting the simulated structure to spots found in the LEED pattern (available from Fritz & Sojka GbR)

⇒ can be used for conventional LEED, MCP-LEED, and SPA-LEED, regardless of the brand

to get an impression, you may take a look here:


LEEDCal 2013 (v 4.1)

The free LEEDCal software package provides a powerful algorithm to determine and correct systematic distortions in LEED images. Easy to operate via its graphical user interface, LEEDCal will automatically generate a correction matrix upon analyzing a calibration sample (exhibiting a well-known surface structure). This calculated matrix can be saved and applied later on, by using LEEDCal_corr, to rectify all future diffraction patterns recorded with the same LEED device. This works also in batch mode! The results allow accurate interpretation of lattice constants/epitaxial relations when used in combination with the LEEDLab software or by your own methods.


LEEDCal 2018 (v 1.2)

LEEDLab is a software packagemaking it possible to simulate (free) and quantitatively analyze (available from Fritz & Sojka GbR) LEED patterns. It has been developed to enable geometric simulations of complex surface structures, allowing objective determination of the lattice parameters and epitaxial relations. For carefully calibrated devices (using LEEDCal and LEEDCal_corr) an unsurpassed accuracy of typically 1% can be attained.

Required Software/ Installation Instructions

For LEEDCal 2013 the MATLAB Runtime R2013a (8.1)) 64-bit (direct download link) is required.

For LEEDLab 2018 the MATLAB Runtime R2018a (9.4)) 64-bit (direct download link) is required.

Note that the MATLAB Runtime required for LEEDLab 2018 is a different one from that needed for LEEDCal 2013, and that MATLAB Runtimes are not downwards compatible.
After the installation of any MATLAB Runtime a restart of the computer is highly recommended.
