THERMAL NEUTRON DEPTH PROFILING
NPI Rez - Thermal Neutron Depth Profiling (TNDP).study of diffusion of some light elements in selected ISOL targets
Diffusion coefficient D can be deduced from the broadening of the TNDP profiles
D = D0 e-e/kT
D0 – pre-exponential constant
– activation energyk – Boltzman constantT – temperature (in 0K)
Example of the TNDP analysis:350 keV 10B implanted into BaF2 annealed 60 min at 4170C. The analysis of the broadening of the boron profiles gives the diffusion coefficient D = 2 x 10-13 cm2.s
