We have investigated the structural and electrical behavior of Fe centers introduced in InP by high temperature ion implantation. The effect of post-implantation annealing treatments on the crystal damage and the lattice location of the Fe atoms was studied by PIXE-RBS-channeling measurements. Current-voltage measurements and simulations were used to characterize the electrical properties due to the presence of Fe-related deep traps. The results show that the background n-doping density plays a crucial role in controlling the annealing behavior and the electrical activation of the Fe centers.

Abstract
We have investigated the structural and electrical behavior of Fe centers introduced in InP by high temperature ion implantation. The effect of post-implantation annealing treatments on the crystal damage and the lattice location of the Fe atoms was studied by PIXE-RBS-channeling measurements. Current-voltage measurements and simulations were used to characterize the electrical properties due to the presence of Fe-related deep traps. The results show that the background n-doping density plays a crucial role in controlling the annealing behavior and the electrical activation of the Fe centers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
