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…
Investigation of a 90 Degree Spherical Deflecting Analyzer Operated in an Asymmetrically Charged Configuration
Chong-Yu Ruan, Scott Nguyen, Manfred Fink
The electron optics of a 90 degree spherical deflecting analyzer (SDA-90) is investigated with an imaging matrix formalism. As a preanalyzer in the UTA-neutrino experiment, high tr…
