The curve trace plots you can see on this site are made with an oscilloscope and are the amount of current that a substance allows to flow through it across a range of voltages (from -2.5V to 2.5V) unless otherwise specified. Some of these traces of naturally grown minerals seem similar to silicon or germanium diodes that are made in factories as electronic components, but a lot of them are quite a lot stranger.
Curve plots only tell part of the story with these semiconductors, as they are 'snapshots' of their behavior, and do not provide information on noise characteristics or how the material 'flips' between different modes of conduction. Sonification is another approach, which is of course the broader purpose of this project!
