dc.description.abstract | Joule heating is generally acknowledged as the main driving force behind Flash Sintering. However, this view is
challenged by the presence of athermal phenomena and the similarities between the flash process and dielectric
breakdown. This work offers new insights into flash as an electrical runaway. Using current ramps to perform
flash experiments on zinc oxide, two distinct stages within the process were revealed by electrical, thermal and
microstructural measurements: a field-dominated regime where the flash event is triggered and a subsequent
current-dominated regime associated with power dissipation. The contribution of each regime to the whole flash
process was found to be determined by the initial resistivity of the sample. Furthermore, impedance spectroscopy
data confirmed field-induced enhancement of conductivity at the flash-onset without significant Joule heating. | es |
