      abstract     = {Flash sintering, a special case of electric field-assisted
                      sintering, results in accelerated densification at lower
                      temperatures than conventional sintering methods. However,
                      the mechanisms remain elusive despite the wide application
                      potential. In-situ electron microscopy studies reveal
                      shrinkage of ZnO green bodies due to both heating and
                      heating/biasing but show no obvious effect of the current on
                      the behavior. In contrast, thin epitaxial ZnO films
                      deposited on an Al2O3 substrate undergo a clear flash event
                      during in-situ voltage application in the TEM, providing the
                      first observation of flash sintering of a thin film. The
                      specimen was captured in the high conductivity state where
                      grain boundary motion was observed. The microscopic origins
                      of the high conductivity state could not be detected, but
                      may have the same underlying physical origin as the high
                      conductivity memristive state.},
