Abstract : This document describes a quadrant avalanche photodiode with large surface areas is made using photolithographic planar technology. The use of proton bombardment creates semi-insulating material around the quadrants. Semiinsulating material prevents cross-talk between quadrants. The Schottky barrier quadrant detectors were fabricated using GaAs(1-x) Sb(x) ternary alloys grown epitaxially on heavily doped GaAs substrates.
