Formation of Defects in Displacement Cascades in Molybdenum: Simulation of Molecular Dynamics

Аннотация

In this work, the process of the formation of defects and their clusters in collision cascades has been investigated in molybdenum by the molecular dynamics method. We have obtained results on the number of arising defects, the fraction of defects in clusters, and cluster-size distribution. Their dependence on the energy of primary knocked-on atom and temperature of the material has been studied. A comparison with calculations using the SRIM program and NRT model has been made. The effect of annealing defects after the development of cascades on the number of arising defects has been examined.
