Non-thermal structural transformation of diamond driven by x-rays

Publikováno v: Structural Dynamics, Vol 10, Iss 5, Pp 054502-054502-7 (2023)

Intense x-ray pulses can cause the non-thermal structural transformation of diamond. At the SACLA XFEL facility, pump x-ray pulses triggered this phase transition, and probe x-ray pulses produced diffraction patterns. Time delays were observed from 0

We reveal the microscopic origin of the ovonic threshold switching mechanism.
Fifty years after its discovery, the ovonic threshold switching (OTS) phenomenon, a unique nonlinear conductivity behavior observed in some chalcogenide glasses, has b
