Animations
In all of these animations, one sphere illustrates the position
of an atom. When atoms change colors, the color scale is
a logarithmic scale in kinetic energy, unless otherwise indicated
in the color legend. Most views are
a 2-4 atom layer thick cross section through the center
of the simulation cell. .
Tutorial animation | Background/explanation |
1 keV Xe -> Cu |
[WMV] 1 keV Xe ion irradiation of Cu, with a combined
3D and cross-sectional view of the same event. Color scaling by kinetic energy
of atoms. |
1 keV Xe -> Cu |
[WMV] 1 keV Xe ion irradiation of Cu, same
as previous but without 3D view.
Color scaling by kinetic energy
of atoms. |
3 keV Au -> Au |
[WMV] 3 keV self-recoil in Au, includes visualization
of defect formation and migration after the collisional
stage of the cascade. Note that since the simulation
uses periodic boundaries, there is eventually perfect
defect recombination, in reality a few of the defects would
likely escape the initial cascade region. |
10 keV Au -> Au |
[WMV] 10 keV self-recoil in Au, includes display of
maximum kinetic energy of any atom in system to illustrate
thermalization. Cross-sectional view. |
10 keV Fe -> Fe |
[WMV] 10 keV self-recoil in Fe plotted in three
different color scales: kinetic energy, potential energy
and atom displacements. This illustrates the problem
with the NRT-dpa standard and the reason for us to develop
the improved arc-dpa and rpa equations [Nature comm. 9, 1084 (2018)] |
1 keV Si -> Si: 1000 ion trajectories |
[WMV] Trajectories of 1000 1 keV Si ions incoming on Si (001), plotting only ion position. Theta varied between 0 and 10 degrees. MDRANGE simulations. |
30 keV Xe -> Au |
[AVI] 30 keV Xe impact on Au (7 degrees off the 100 direction i.e. partly channeled). Cross-sectional view |
5 keV Ar -> Ni |
[WMV] 5 keV Ar impact on Ni, tilted top view |
5 keV Ar -> Ni |
[WMV] 5 keV Ar impact on Ni, cross section (same event as above) |
500 eV Au -> Cu |
[AVI] 500 eV Au impact on Cu (made for demonstration only,
can you spot the minor cheat used only for plotting?). Cross sectional view. |
10 keV Au -> Cu3Au |
[GIF] Disordering by a 10 keV Au -> Cu3Au cascade.
Cross-sectional view, colors are atom type, yellow being Au. |
5 keV Si -> Si |
[WMV] 5 keV Si recoil in Si, view through whole cell |
