Researchers identify record-setting electron mobility in a new crystal film
Researchers at MIT, DEVCOM Army Research Laboratory, The Ohio State University, and University of Ottawa have reported unique electron mobility in a new crystal film that could be the basis for wearable thermoelectric and spintronic devices.
A material with a high electron mobility is like a highway without traffic, and the electrons that flow into the material experience movement without any obstacles to slow or scatter them off their path. The higher a material’s electron mobility, the more efficient its electrical conductivity, and the less energy is lost or wasted as electrons move through. Advanced materials that exhibit high electron mobility will be essential for more efficient and sustainable electronic devices that can do more work with less power.
