| Abstract: | Ordered arrays of upright nanocolumns of chalcogenide glass were fabricated by combining the oblique angle deposition technique with substrate rotation. Self-assembled close-packed arrays of polystyrene spheres of 200 nm and 500 nm in diameter were used as templates. Our method allows the fabrication of GeSbSe nanocolumns of controlled height, cross-sectional diameter and two-dimensional distribution. Finally, preliminary optical characterization suggests the possible use of the ordered arrays of GeSbSe nanocolumns in optical devices, in particular photonic crystals. |
