Three-dimensional implantation distribution of lithium implanted into pyrographite, as revealed by solid state tomography in combination with neutron depth profiling
Abstract
We have studied the three-dimensional distribution of 2.5 MeV Li implanted into pyrographite at room temperature by means of modified tomography in combination with neutron depth profiling. Our new findings essentially reconfirm earlier results (D. Fink et al., J. Appl. Phys. 58 (1985) 668 [1]; Radiat. Eff. and Def. in Solids 114 (1990) 21 [2]) which indicated the presence of some radiation-enhanced mobility of the implanted lithium. This diffusion is anisotropic. It preferentially proceeds into the radial direction.
