Scripts + Programs

Analysis Programs

  • FIJI - scientific image anaylsis software
  • Gwyddion - free analysis software for Atomic Force Microscopes (AFMs) and other 3D data.
    • Sophisticated leveling, slicing, roughness analysis functions etc.
    • Can open Bruker NanoScope files, from the AFM
  • ProfilmOnline.com (Filmetrics) - online analysis/storage/sharing of 3D topographical data and images.
    • You can share an interactive 3D render of your AFM or Wyko scans with this tool.

General Calculators

  • Anaconda Python
    • A free Matlab-like IDE and GUI, using the Python language. The Spyder interface is modeled after Matlab.
    • Includes the scientific Python libraries needed for array math (numpy), plotting (matplotlib), data science (pandas) and many others. Many open-source packages are available to extend capabilities. The PyVisa module adds equipment control capabilities for automated measurements.
  • Wolfram Alpha
    • A versatile online interpreter/calculator, allowing calculations such as "Volume of 1.5g of Silicon", "melting point of SiO2" or "520°C in Fahrenheit".
  • nk.py (Demis D. John)
    • Python functions for returning n (ref. idx.) & k (ext. coeff.) of various NanoFab thin-films at a specified wavelength (aka. dispersion models).

Python Scripts

These scripts are best run in the Spyder IDE, which is easily installed via Anaconda, Python(X,Y), or by directly compiling Spyder using a command-line package manager.

  • Keithley I-V Sweep
    • Sweep voltage and plot current vs. voltage using a Keithley SMU.
    • Already installed at the Probe Station in Bay 4, and on the QFI Thermal Microscope (Use Python(X,Y) to run).
    • Requires the pyvisa python module.
  • QFIScope Thermal Analysis
    • Import 2D temperature data from the IR Thermal Microscope (QFI) and plot temperature profiles at user-specified locations.
    • Already installed on the QFI Infrared Microscope.
  • Laser Etch Monitor Simulation in Python
    • Simulate your laser endpoint signal as you dry-etch through a stack of thin-film layers, using an open-source electromagnetics module.
