LEED and STM pattern analysis, in your browser.
Fit lattices to low-energy electron diffraction patterns, determine epitaxy matrices and coincidence, correct the distortion of your LEED optics, index patterns automatically and analyse the Fourier transform of STM images – without installing anything.
Lattice fitting
Click spots, fit substrate and overlayer lattices with error estimates and get the epitaxy matrix and coincidence type.
Distortion calibration
Correct the radial and tangential distortion of your LEED optics from an energy series of a known surface.
Automatic indexing
Find the overlayer lattice automatically from the detected spots, as a separate tool next to the manual workflow.
STM Fourier analysis
Load STM images, compute and inspect the FFT and fit the same lattice models in reciprocal space.
Publication figures
Export vector figures with the measured and simulated pattern and all fitted parameters including errors.
