Electrically switchable vacancy state revealed by in-operando positron experiments
Ric Fulop, Laurence Lyons, Robert Nick +6
Whether the flash state in electrically driven solids involves non-equilibrium defect production or is accounted for by Joule heating alone has been debated since 2010. Using posit…

Critical Activation Voltage for Phonon-Mediated Field-Driven Phenomena
Ric Fulop, Neil Gershenfeld
Field-driven phenomena, from flash sintering to electromigration, exhibit threshold fields spanning six orders of magnitude. We show their product with the onset activation coheren…
