The 600 nm AlGaInP epitaxial wafers were cleaned using acetone and methanol to remove the organic contamination, and were followed by etching of the n-GaAs substrate (back side) and the p-GaP window layer (front side) in an H 2 SO 4:H 2 O 2:DI water (3:1:1) solution. After the cleaning and wet-etching processes, bonding pads were patterned on ...

Composite transparent conductive layers (TCLs) were deposited on the GaP window layer of p-side-up thin-film AlGaInP light-emitting diodes (LEDs) in order to enhance their light-extraction efficiency.The composite TCLs were fabricated from aluminum-doped zinc oxide (AZO) layers grown through atomic-layer deposition and pulsed-laser deposition. The results …

An omnidirectional reflector (ODR) consisted of (MgF 2)/Ag was employed in AlGaInP-based vertical red light-emitting diodes (LEDs) in order to increase the light extraction hence the wall-plug efficiency.In this structure, the dielectric MgF 2 layer with low refractive index acted as current blocking and reflection enhancing layer. The cylindrical AuZn alloy micro …

Light extraction from LED structures is a major challenge in the development of quaternary (Al 1 − xGa x) 0.5 In 0.5 P-based light-emitting diodes (LEDs) owing to its being limited by substrate absorption and total internal reflection. One approach for improving light extraction is to minimize total internal reflection by inserting a middle-refractive-index material between the …
