Atomic Transport by Ion Beam Mixing in the Radiation Enhanced Diffusion Region

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

In order to study atomic transport in the radiation enhanced diffusion (RED) region, Pd/Co bilayers were intermixed by 80keV Ar+ in the temperature range from 90 K to 700 K. The critical temperature for the onset of RED was found to be ∼ 400 K, and the transported amount of Pd atoms was found to be always larger than that of Co in the RED region. This result cannot be explained by pre-existing models. Thus we have developed a comprehensive model for atomic transport in the RED region including size effect, damage controlled effect, and cohesive energy effect.
