使发光

Another approach in enhancing the light extraction efficiency of AlGaInP LED was accomplished using a surface roughening process. In this process, the Au(170 nm)/AuBe(260 nm)/Au(170 nm) ohmic contact layers were first deposited on the GaP window layer. After the alloy annealing process (480°C for 10 min), the Be atoms will diffuse into the GaP top layer and form non-uniform clusters. The LED samples were then immersed into a mixture 3H3PO4:1H2O2:1H2O solution for 6 min, resulting in a rough GaP surface. The luminous intensity of the AlGaInP LED can increase from 42 to 50 mcd, that is, an 18% enhancement can be achieved via the present non-photolithography surface roughening process.Keywords: LED, AlGaInP, Cu substrate, Reflector, Surface roughening
