Electronically Driven Fragmentation of Silver Nanocrystals Revealed by Ultrafast Electron Crystallography
Ramani K. Raman, Ryan A. Murdick, Richard J. Worhatch +4
We report an ultrafast electron diffraction study of silver nanocrystals under surface plasmon resonance excitation, leading to a concerted fragmentation. By examining simultaneous…
Direct observation of optically induced transient structures in graphite using ultrafast electron crystallography
Ramani K. Raman, Yoshie Murooka, Chong-Yu Ruan +3
We use ultrafast electron crystallography to study structural changes induced in graphite by a femtosecond laser pulse. At moderate fluences of ~< 21mJ/cm^2, lattice vibrations are…
Photovoltage Dynamics of the Hydroxylated Si(111) Surface Investigated by Ultrafast Electron Diffraction
Ryan A. Murdick, Ramani K. Raman, Yoshie Murooka +1
We present a novel method to measure transient photovoltage at nanointerfaces using ultrafast electron diffraction. In particular, we report our results on the photoinduced electro…
Dynamics of Size-Selected Gold Nanoparticles Studied by Ultrafast Electron Nanocrystallography
Chong-Yu Ruan, Yoshie Murooka, Ramani K. Raman +1
We report the studies of ultrafast electron nanocrystallography on size-selected Au nanoparticles (2-20 nm) supported on a molecular interface. Reversible surface melting, melting,…
