Abstract :
The redistribution of Cr is shown to be responsible for the formation of deep trails in the electron density profiles of certain semi-insulating GaAs substrates following Se ion implantation and annealing, and for the formation of spurious n-type conducting layers in those substrates following encapsulation with Si3N4and annealing without implantation.
