We investigated the Fe ion implantation and annealing processes used to obtain semi-insulating buried layers in InP epitaxial structures for current confinement in laser device applications. SIMS and RBS-channeling were used as analytical tools. The results show that the annealing is a rather complicated process when the implant causes sample amorphization: high surface reactivity, anomalous dopant diffusion and segregation at damage sites together with inhomogeneous lattice reconstruction are observed.

Abstract
We investigated the Fe ion implantation and annealing processes used to obtain semi-insulating buried layers in InP epitaxial structures for current confinement in laser device applications. SIMS and RBS-channeling were used as analytical tools. The results show that the annealing is a rather complicated process when the implant causes sample amorphization: high surface reactivity, anomalous dopant diffusion and segregation at damage sites together with inhomogeneous lattice reconstruction are observed.File in questo prodotto:
