Just like the artefact found in ferroelectric hysteresis loops, the nearly identical NDR effect shown in Sr3Co2Fe24O41, TiO2, Al2O3, glass and even banana skins is confirmed to be a kind of water behavior. The combination of water-induced tunneling effect, water decomposition and absorption plays a crucial role in the NDR effect. The results and mechanism demonstrated here illustrate that much attention should be paid to the chemical environment when studying electrical properties of materials/devices.
