Generation of misfit dislocations in a core-shell nanowire near the edge of prismatic core
Source abstract
Abstract
The misfit strain relaxation via generation of partial and perfect misfit dislocations and their di-poles at the interface in core-shell nanowires with faceted cores is considered. The core has the shape of a long parallelepiped of a square cross-section and placed symmetrically with respect to the cylindrical shell surface. The energy change caused by dislocation generation in such nanowires is calculated. Critical conditions for the onset of such dislocations are calculated and analyzed. The energy barriers for the dislocation generation are defined with respect to different values of the nanowire parameters. The preference of dislocation configuration and generation sites in the nanowire are determined.
