From: Cr incorporated phase transformation in Y2O3 under ion irradiation
(a) TEM image of the trilayer structure after irradiation with 10 MeV Ni ions. The yellow dashed box indicates the region that is shown in higher magnification in (c). (b) The corresponding diffraction pattern uncovers an irradiation-induced monoclinic phase. (c) An amorphous layer with a thickness of 18 nm is generated at the M/O interface after irradiation. The pristine cubic Y2O3 transforms to the monoclinic phase. (d) Dark field STEM image of irradiated multilayers. (d1–d3) EDS chemical analyses at different regions indicate the situation of Cr diffusion at different boundaries.
