On May 2, the magazine Semiconductor Today reported the innovative study of NJUPT on Near-UV homogeneous integrated optoelectronic chips in News Features.
Based on a Silicon Substrate Nitride Wafer, Professor Wang Yongjin of NJUPT together with professor Hiroshi Amano, an overseas master from the National Micro-Nano Devices and Information System Innovation Introduction Base who won the Nobel Prize in Physics in 2014, obtained a 0.8mm diameter transferable near-UV homogeneous integrated optoelectronic chip for the first time, further verifying the coexistence of the emission and detection of quantum well diodes. The research was published on April 13, 2018 (Appl. Phys. Express 11 051201), the first author of which was Qin Chuan, a postgraduate student, and has been downloaded more than 100 times. Based on the physical phenomenon of coexistence, Prof. Wang developed the full-duplex visible light communication chip. In the past two years, Semiconductor Today has featured the study of Prof. Wang’s research group on homogeneous integrated optoelectronic chips, establishing China's leading position in this field.
