Structure and energy of the partial dislocation cores in GaAs

A methodology for investigating isolated α and β partial dislocations in III–V semiconductors is presented. Using this method the 30° and 90°, α and β partial dislocations in GaAs are investigated. The structures of the proposed core reconstructions are investigated. For the 90° partials, two recons...
