Abstract
We propose to fabricate GaAlAs/GaAs multi-layer microtips for scanning near-field optical microscopy (SNOM) using the anisotropic etching. The etching was performed in a solution of H3PO4:H2O2:H2O, operating at the temperature of 10 degrees C. We obtained the pyramid-shaped microtips with four etched facets and with a radius of curvature at the apex lower than 50 nm.
