EIS potential scan or current scan

EIS Potential scan or current scan is an electrochemical technique that can be applied with any EIS-capable PalmSens potentiostat. ‘E dc scan’ means that multiple measurements will be conducted with different dc-potential levels, starting from ‘E begin’ and ending at ‘E end’ in increments determined by the ‘E step’. At each dc-potential level, a single fixed frequency is applied, or a frequency scan is made, according to the set ‘Frequency type’.
‘E dc scan’ with a fixed frequency corresponds to the same applied signal as Mott-Schottky experiment. PSTrace and MultiTrace allow plotting Capacitance versus E dc. However, the final Mott-Schottky plot must show Capacitance elevated to -2 (C^-2) instead. This can be achieved by handling the data elsewhere in a later stage in a spreadsheet software of your preference.

With the same principle, ‘i dc scan’ is available for the instruments featuring Galvanostatic EIS. Naturally, in this case the current is set as it is the controlled value.
