- Abstract
- Atomic transport in the radiation enhanced diffusion (RED) region has been studied from the shifts of a marker layer in ion beam mixed Pd/Co and Pd/Au bilayers. 80 keV Ar+ with a dose of 1.5 × 1016 ions/cm2 were irradiated into the bilayers at temperature region from 90 K to 700 K. In the Pd/Co system, the atomic flux of Pd (JPd) transported across the interface is nearly same with JCo in the thermal spike region, while JCo is always larger than JCo in the RED region. However, in the Pd/Au system, JPd is nearly same with JAu in both of the thermal spike and RED regions. We have developed a model to describe the atomic transport in the RED region, which predicts that the atom with small cohesive energy has more mobility than that with large cohesive energy.
