SXM Processing Tool

G80SXM

G80SXM is a tool written in python to quickly analyse and create figures for Nanonis SPM data (STM/STS/nc-AFM). I am actively developing this tool so if you have any suggestions or find any bugs, feel free to create an issue. The provided ./ExampleData used to create these figures was obtained in our lab at Monash University (see publications here and here).

Installation

Install with pip: pip install g80sxm

Usage

There are a number of panels in the gui, each with a specific function. See below figures for some examples. Hovering over buttons in the GUI will also provide help. Sessions can be saved and loaded via '.g80' files so you can pick up where you left off.

• Easily overlay atoms with correct scaling from custom .xyz files
• Automatically or manually locate markers on the main figure that correspond to spectrum locations
• Quickly fit spectra with
  • Reference curves/Other STS curves
  • Gaussian
  • Fermi-Dirac
  • More

• Visualise grid data from .3ds files (middle panel)
• Easily pull out individual curves from a grid
• Ability to average curves from several pixels within a grid. In this example, each spectrum plotted is an average of three spectra from the middle panel as denoted by the blue, orange and green crosses

• Plot multiple 1D cuts through data
• Label and colour line cuts
• Fit profiles to accurately determine step edge heights
• Easily add, position, and style inset figures

• View FFT and label peaks

• Apply rolling and high-pass filters
• More filters being added soon

g80sxm's Issues

Step edge height when fitting line segments in profile panel

Currently, the step edge height is calculated based on the height of the midpoint of adjacent linear fits. this should be changed to calculate the step edge height from the endpoint and start point of adjacent lines
