| Research Abstract |
In several semiconductors, nano-scale cellular structure is formed on their surfaces by ion irradiation. We aimed to establish the novel nano-fabrication technique utilizing this astonishing phenomenon and investigated nanocell fabrication for GaSb, InSb and Ge. The cell lattice with 100 nm cell interval on InSb surface develops regularly without secondary void formation by irradiation at room temperature, however, the regularity is insufficient at lower temperature. GaSb reveal the inverse results, that is, the secondary voids are created at room temperature and the cell lattice development is better at lower temperature. Furthermore filling in the cells is tried.
