Abstract
An InGaN-based LED epitaxial wafer and a fabrication method thereof are disclosed, wherein the InGaN-based LED epitaxial wafer includes: a substrate; an InGaN layer, formed on a surface of the substrate, having an In content between 40% and 90%, so as to ensure that the LED epitaxial wafer is capable of emitting long-wavelength light or near-infrared rays; a p-type metal oxide layer, formed on a surface of the InGaN layer facing away from the substrate, acting as a hole injection layer for the InGaN layer.
