Study of the growth of NiO on highly oriented pyrolytic graphite by X-ray absorption spectroscopy
In this work, we present a X-ray absorption spectroscopy (XAS) study of the growth of NiO on highly oriented pyrolytic graphite (HOPG). NiO as been grown by reactive evaporation of metallic Ni in an oxygen atmosphere (2× 10−5 Torr) at room temperature. We paid special attention to he study of the early stages of growth. Both, Ni 2p and O 1s core-level XAS spectra were measured. For large NiO co...
متن کاملUltrafast X-ray Scattering from Molecules.
We present a theoretical framework for the analysis of ultrafast X-ray scattering experiments using nonadiabatic quantum molecular dynamics simulations of photochemical dynamics. A detailed simulation of a pump-probe experiment in ethylene is used to examine the sensitivity of the scattering signal to simulation parameters. The results are robust with respect to the number of wavepackets includ...
متن کاملX-ray Scattering from PHELIX Plasmas
Warm dense matter (WDM) is a regime where neither classical plasma physics nor condensed matter models are applicable. In the former this is because of the effects of strong coupling and degeneracy and the breakdown of the statistical averaging necessary for the Debye screening model. In the latter it is because the temperature at solid density is greater than a small fraction of the Fermi temp...
متن کاملCrumpling of a pyrolytic graphite sheet
Crumpled graphite thin film balls were fabricated with Panasonic Pyrolytic Graphite Sheets (PGS). The fractal dimension, mechanical properties, and electrical conductivity of the crumpled PGS balls have been investigated. The universal local fractal dimension of the PGS balls is found to be 2.58, which is consistent with that of paper balls. The crumpled PGS balls show good mechanical property ...
متن کاملX-Ray Diffuse Scattering
In this research program, modern x-ray scattering techniques are used to study the structures and phase transitions in novel states of condensed matter. We have two principal experimental facilities. At M.I.T. we have three high-resolution computer controlled x-ray spectrometers using either a conventional or high intensity rotating anode x-ray generator. The angular resolution can be made as f...
