Bioinspired broadband antireflection coatings on GaSb

Wei-Lun Min, Amaury P. Betancourt, Peng Jiang, and Bin Jiang
We report an inexpensive yet scalable templating technique for fabricating moth-eye antireflection gratings on gallium antimonide substrates. Non-close-packed colloidal monolayers are utilized as etching masks to pattern subwavelength-structured nipple arrays on GaSb. The resulting gratings exhibit ... [Appl. Phys. Lett. 92, 141109 (2008)] published Wed Apr 9, 2008.
