Abstract
A technique for fabricating tapered-surface structures on GaAs crystals is demonstrated. GaAs crystals are bombarded with low-energy (5 keV) Ar + ions, and the partially masked surfaces are etched with an aqueous solution of FeCl 3-HCl. Effect of the ion bombardmentenhanced etching is utilized to proceed a high-rate lateral etching under the mask, and to reveal a surface with a taper angle of 10-45°, depending on the ion dose.
