Title: Fanghai Zhao: Innovator in Light-Emitting Device Technology
Introduction
Fanghai Zhao is a prominent inventor based in El Monte, CA (US). He has made significant contributions to the field of light-emitting devices, holding a total of 3 patents. His innovative work focuses on improving the efficiency and performance of these devices.
Latest Patents
Fanghai Zhao's latest patents include a method for manufacturing light-emitting devices with an improved active-region. This invention features a light-emitting device that comprises an active-region sandwiched between an n-type layer and a p-type layer. This design allows for lateral carrier injection into the active-region, which reduces heat generation and minimizes additional forward voltage increases associated with bandgap discontinuity. In some embodiments, the active-region is a vertically displaced multiple-quantum-well (MQW) active-region, and a method for fabricating the same is also provided.
Another notable patent is for three-dimensional light-emitting devices and the method for fabricating them. This invention describes a three-dimensional LED structure with vertically displaced active-regions, which includes at least two groups of vertically displaced surfaces on a non-planar substrate. The first group of surfaces is separated from the second group by a vertical distance in the growth direction of the LED structure. The design allows for enhanced performance and efficiency in light-emitting devices.
