    Diffusion of Al in ion-implanted Pd and Pt (1984)
    Springer

    Notizen: Abstract The diffusion coefficients of aluminium have been measured in polycrystalline fcc Pd and Pt. The Al-implanted palladium and platinum samples were annealed at 400°–800 °C and 450°–900 °C, respectively. The aluminium profiles were probed using the nuclear resonance broadening (NRB) technique. Values of (1.41±0.09) and (1.38±0.09) eV for the activation energy and (1.5 −1.0 +5 )×10−6 and (4 −3 +10 )×10−7cm2/s for the frequency factor were obtained for Al in Pd and Pt, respectively. These anomalous results, compared to the “normal impurity diffusion”, were checked using also Al-evaporated samples.

    Annealing behaviour of implanted nitrogen in bulk and evaporated Ni (1987)
    Springer
    Applied physics 42 (1987), S. 263-267 
    Details
    ISSN: 1432-0630

    Notizen: Abstract The diffusion coefficients of nitrogen in N-implanted polycrystalline Ni have been deduced. Both bulk and Ni-evaporated samples implanted with nitrogen were annealed at 150–500° C. The nitrogen profiles were probed using the nuclear resonance broadening technique. The value of 0.99±0.12 eV for the activation energy and (3.0 −2.8 +40 )×10−6 cm2/s for the frequency factor were obtained for implanted N in bulk Ni. The solubilities for both the bulk and evaporated Ni samples are given. In evaporated Ni nitrogen migration is enhanced due to the defects arising during evaporation.

    Radiation enhanced outdiffusion during ion implantation (1979)
    Springer
    Applied physics 19 (1979), S. 199-203 
    Details
    ISSN: 1432-0630
    Schlagwort(e): 61.70T ; 61.80J
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Maschinenbau , Physik
    Notizen: Abstract For a systematic prediction of the radiation-enhanced outdiffusion occurring during implantation, the use of a model based on the effect of vacancy flow on diffusion is described. The model agrees reasonably well with experiments in all twentysix measured cases. For the systematic understanding of the radiation enhanced outdiffusion, an approximative diagram based on the activation energy of self-diffusion is constructed for all pure elements and its application possibilities are discussed.
