Electrical Tomography Software
Res2dinv
This very popular software, developped by M.H.Loke, uses the method involving the Sasaki minimum squares inversion (1992) to produce a 2D sub-soil model starting from the data of apparent resistivity (up to 2000 electrodes). It is completely automatic and does not require that the user formulates a starting model. When using a state-of-art computer, the inversion of a single pseudosection will require only a few minutes.RES2DINV supports spreading types like Wenner, Schlumberger, Pole-Pole, Pole-Dipole, line Dipole, equatorial Dipole and other non-conventional spreading types.

Junction Measurement and Analysis
Materials Development Corporation
A comprehensive set of analyses for junction diode or Schottky barriers begins with C-V data gathering that adjusts the voltage step to the slope of the C-V characteristics. This assures an optimum set of C-Vdata whether the voltage range is small or large. Doping profile and resistivity profile are both available at the touch of a key. Plots of 1/C2 - V or Log(C) - Log (V+ phi) show doping uniformity and doping slope factor. Exclusive recalculation options allow adjustment of stray capacitance and area to facilitate calibration using a standard reference wafer of known doping or resistivity.
