Femtosecond x-ray experiments in combination with a new theoretical approach establish a direct connection between electric properties in the macroscopic world and electron motions on the time and length scale of atoms. The results open a new route for understanding and tailoring the properties of ferroelectric materials.

The existing surface termination technique using hydrogen to stabilize the diamond's structure for application in electronic power devices results in two-dimensional hole gas layers (2DHG). Attempting to remove these layers using oxygen-termination roughens the diamond surface and leads to degradation of the device performance. To overcome this, researchers have removed 2DHG from diamond using water vapor annealing and maintained an atomically flat surface.
