China's first internationally innovative field-effect modulated photodiode for optical communication and optical computing
I learned from the University of Science and Technology of China that Professor Sun Haiding's research team collaborated with the team of Academician Liu Sheng of Wuhan University to propose a novel three-electrode photoelectric PN junction diode structure for the first time in the world, construct a new method for carrier modulation, and achieve effective control of the photoelectric characteristics of the diode by an external electric field applied to the third port. The relevant research results were recently published online in the journal “Nature • Electronics”. Researchers said that since the device structure and manufacturing process are very simple, the proposed new field-effect modulated photodiode architecture can be widely used in other active optoelectronic integrated chips and device platforms made of various semiconductor materials.
