Title: Innovations of Liangjun Wang in Light Emitting Diodes
Introduction
Liangjun Wang is a prominent inventor based in Xiamen, China. He has made significant contributions to the field of optoelectronics, particularly in the development of light-emitting diodes (LEDs). With a total of 4 patents to his name, his work has advanced the technology and performance of LED devices.
Latest Patents
One of his latest patents is titled "Light Emitting Diode and Fabrication Method Thereof." This invention describes a light-emitting diode that includes a first-type nitride region, a light-emitting region, and a second-type nitride region. The first-type nitride region consists of alternating first and second nitride layers, with the second nitride layers having high-doped emitting points directed towards the corresponding first nitride layer. The second-type nitride region also features alternating third and fourth nitride layers, where the doping concentration of the fourth nitride layer is higher than that of the third. By adjusting the thickness of these layers during growth cycles, the horizontal expansion of current can be significantly enhanced, thereby improving LED performance.
Another notable patent is for a "Nitride Light-Emitting Diode." This invention includes a substrate, an n-type nitride layer, a light-emitting layer, a p-type nitride layer, a p+ layer, an AlInN layer, an n+ layer, and an ITO transparent electrode. The design incorporates a tunneling structure with an AlInN intermediate layer, which generates polarization charges at the tunneling junction interface. This innovation increases the tunneling probability of holes and reduces contact resistances, further enhancing the efficiency of the LED.
