Ultrafast optically-induced melting of trimer clusters in 1T'-TaTe2 (JW7A.112)

Presenter: Robert Kaindl, Lawrence Berkeley National Laboratory

Relativistic ultrafast electron diffraction is used to track the transient structural dynamics of tantalum ditelluride. We observe rapid photo-induced melting of its low-temperature trimer superstructure as driven by intra-trimer charge transfer.
