Journal ArticleDOI
Direct imaging of transient molecular structures with ultrafast diffraction.
Hyotcherl Ihee,Vladimir A. Lobastov,Udo M. Gomez,Boyd M. Goodson,Ramesh Srinivasan,Chong-Yu Ruan,Ahmed H. Zewail +6 more
TL;DR: This direct imaging of reactions was achieved using the third-generation apparatus equipped with an electron pulse, a charge-coupled device camera, and a mass spectrometer to demonstrate the vastly improved sensitivity, resolution, and versatility of UED for studying ultrafast structural dynamics in complex molecular systems.
Journal ArticleDOI
Ultrafast Electron Crystallography of Interfacial Water
TL;DR: The structures were determined to be dominantly cubic, but each undergoes different dynamics after the ultrafast substrate temperature jump, and changes in local bond distances with time elucidated the structural changes in the far-from-equilibrium regime at short times and near-equilibration at long times.
Journal ArticleDOI
Ultrafast electron diffraction (UED) a new development for the 4D determination of transient molecular structures
TL;DR: In this paper, the authors highlight the advances made at Caltech, with emphasis on the principles of UED, its evolution through four generations of instrumentation (UED-1 to UED-4) and its diverse applications.
Journal ArticleDOI
Decoupling of Structural and Electronic Phase Transitions in VO 2
Zhensheng Tao,Tzong-Ru Han,Subhendra D. Mahanti,Phillip M. Duxbury,Fei Yuan,Chong-Yu Ruan,Kevin Wang,Junqiao Wu +7 more
TL;DR: Using optical, TEM, and ultrafast electron diffraction experiments, it is found that single crystal VO(2) microbeams gently placed on insulating substrates or metal grids exhibit different behaviors, with structural and metal-insulator transitions occurring at the same temperature for insulators and metal substrates.
Journal ArticleDOI
Direct observation of optically induced transient structures in graphite using ultrafast electron crystallography.
TL;DR: This work uses ultrafast electron crystallography to study structural changes induced in graphite by a femtosecond laser pulse, tracing the governing mechanism back to electronic structure changes following the photoexcitation.
