Description

The sheet resistivity of oxygen-implanted n+-Al0.48In0.52As grown on InP was measured as a function of oxygen ion dose and post-implant annealing temperature. The sheet resistivity is >105 Ω/D'Alembertian after implantation for doses in the range 1012--8x1013 cm-2, and increases to >107 Ω/D'Alembertian after annealing at 500 degree C. Temperature-dependent Hall measurements show that the resistivity of this compensated AlInAs has a thermal activation energy of 0.68 eV. Above 600 degree C the damage-related compensation is removed and the material is returned to its original resistivity. We find no thermally stable, oxygen-related deep acceptors in AlInAs, in contrast to the results for AlGaAs
