Summary form only given. Solids are known to have crystalline structures, which are often disrupted by defects. Among them, dislocations are topological defects representing permanent deviations of atoms from their ideal periodicity in the crystal. Dislocations define many properties of crystalline materials: the motion of dislocations at the microscopic scale is known to be responsible for macroscopic deformations of materials under applied stress by sliding motion of neighbouring atomic planes over each other [1]. Experimental observations of dislocations in real crystalline solids are very difficult. Here we use molecular dynamics simulation and an experimental model system - complex plasma to study dislocation motion.
