| N 22:54 | Negative resistance diffhist +636 Cornish semiconductor talk contribs (Created page with "Negative resistance is when a device or material allows more current to flow as voltage across it is *decreased*, or vice versa, less current is passed with an *increase* in voltage. It's principle use to to create very high speed oscillators, in the microwave range. Some natural semiconductors also seem to have this capability, Cornish arsenopyrite and wolframite seem to occasionally. In a curve plot it looks like a reverse loop, it's hard to capture as it's ra...") | ||||
