HRTEM study of ion beam irradiation induced amorphization in ceramic materials

PDF Version Also Available for Download.

Description

Computer analysis indicates that amorphization occurs directly within the displacement cascade in Ca{sub 2}La{sub 8}(SiO{sub 4}){sub 6}O{sub 2}. The lack of discrete amorphous cascade domains in the image in irradiated {beta}-SiC indicates that amorphization occurs by point defect buildup in {beta}-SiC. The HRTEM image of UO{sub 2} contains no visible damage even after a very high ion dose at 20 K.
