摘要: A high performance, highly reflective ohmic contact, in the visible spectrum (400 nm–750 nm), has the following multi-layer metal profile. A uniform and thin ohmic contact material is deposited and optionally alloyed to the semiconductor surface. A thick reflector layer selected from a group that includes Al, Cu, Au, Rh, Pd, Ag and any multi-layer combinations is deposited over the ohmic contact material.

摘要: A light emitting device includes a heterojunction having a p-type layer and an n-type layer. The n-electrode is electrically connected to the n-type layer while the p-electrode is electrically connected to the p-type layer. The p and n-electrodes are positioned to form a region having uniform light intensity.
