Atomistic simulations of displacement cascades in Y2O3 single crystal

(a) The averaged distortion index and the Y-O bond length of the Y2O3 octahedra as a function of the simulation time for 5 keV PKA. (b) Shows the nearest neighbourhood of one of the Y ions as a function of simulation time, showing the destruction and the recovery of the YO6 octahedron during the cascade corresponding to 5 keV Y PKA.84
