Iron Oxide Electron Hopping (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption Iron oxide (rust) is a poor electrical conductor, but electrons in iron oxide can use thermal energy to hop from one iron atom to another. A Berkeley Lab experiment has revealed exactly what happens to electrons after being transferred to an iron oxide particle.
