Ion irradiation of InSb yields not only amorphization but also causes the material to become porous. This irradiation-induced porosity in InSb has been investigated using implantation of 1 MeV 69Ga+ ions. Initially, voids form which then develop into a sponge-like structure. Further irradiation generates a network of rods ∼20 nm in diameter. The precursors to porosity, i.e. small voids and dislocation loops, are apparent with transmission electron microscopy in the damaged region below the...[Show more]
