"# Activity 3: Adsorbates and the single scattering approach\n",
|
||||
"\n",
|
||||
"Photoelectron diffraction is widely used to study the adsorption of atoms or molecules on a crystalline surface. Photoelectrons from adsorbates are scattered by the underlying surface, carrying information about the adsorption site, bond length and molecule orientation…. Thanks to a simulation, such information becomes quantitative with a high degree of accuracy.\n",
|
||||
"\n",
|
||||
"Calculations of the multiple scattering using matrix inversion have the great advantage of being exact, including all scattering paths. On the other hand, memory consumption soon becomes a problem as the kinetic energy and number of atoms to be considered increase. As an approximation, it is possible to only consider a single scattering from the emitter to any atom in the cluster. This approximation is extremely computationally fast and gives satisfactory results for adsorbates. We’ll see later that this approach is rather too simplistic for most cases.\n",

"## Oxygen on Rh(001)\n",
|
||||
"In a paper published in 1998, T. Gerber et al. used the quite high backscattering factor of Rhodium atoms to probe the distance of Oxygen atoms adsorbed on a Rhodium surface. Some electrons coming from Oxygen atoms are ejected toward the Rhodium surface. They are then backscattered and interfere with the direct signal comming from Oxygen atoms (see the figure below). They demonstrated both experimentally and numerically with a sinle scattering computation that this lead to a very accurate probe of adsorbed species that can be sensitive to bond length changes of the order of {math}`\\pm 0.02 \\mathring{A}`."

# Welcome to your Jupyter Book
|
||||
|
||||
This is a small sample book to give you a feel for how book content is
|
||||
structured.
|
||||
It shows off a few of the major file types, as well as some sample content.
|
||||
It does not go in-depth into any particular topic - check out [the Jupyter Book documentation](https://jupyterbook.org) for more information.
|
||||
|
||||
Check out the content pages bundled with this sample book to see more.
