Abstract

Significance: An insulator-to-metal phase transition is a process that changes a solid material from being electrically nonconductive to being conductive. The phase transition in vanadium dioxide is a well-studied example where the process can occur in less than a picosecond, making it exciting for ultrafast electronic switches. This paper measures a record speed for the phase transition of 26 fs into a long-lived excited state of the metal that persists out to >60 ps. The extreme UV absorption spectrum of the material is also measured and (together with the ultrafast timescale) belies a structural mechanism that has long been deliberated. The measured femtosecond timescale provides fundamental insight into the electronic speed limits of these complex phenomena.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
