EXAFS Comparison of Crystalline/Continuous and Amorphous/Porous GaSb

Kluth, Susan; Johannessen, Bernt; Kluth, Patrick; Glover, Christopher; Foran, Garry J; Ridgway, Mark C


Ion irradiation of GaSb yields not only amorphization but also causes the material to become porous. For this report, GaSb has been irradiated to a dose sufficient to yield a porous network comprised of 15 nm wide rods. The local structure has been determined by EXAFS and compared with that of a polycrystalline standard. Significant Ga2O3 formation is observed along with Sb-Sb bonding far in excess of the homopolar bonding observed in other amorphous III-V semiconductors.
