41-year-old An Zhenghua is currently a doctoral tutor at Fudan University, and his high school alma mater is Dafeng Middle School. In 1995, he was admitted in advance by the Nanjing University of Science Intensive Program, and after graduation he entered the Institute of Microsystem and Information Technology of the Chinese Academy of Sciences in Shanghai. "Although I settled in Shanghai, I returned to my hometown once or twice a year. My parents are farmers. My father is a farmer and a craftsman. His craft is very good. ' During the interview, An Zhenghua was very humble. He Frankly, the diligent and pragmatic style of his father's generation has also had a profound impact on his growth and scientific research path. Over the years, he has been deeply pursuing the field of thermal electronics research. Today, this research result took nearly 6 years.
On March 29th, the study was titled 'Spatial Imaging of Non-local Thermal Electron Energy Dissipation by Shot Noise'. The related results were published online in the internationally renowned academic journal Science and caused academic attention. What is the use of this research? An Zhenghua said, 'The hot electron phenomenon we discovered may bring some innovations to the device design of the integrated circuit industry in the future. ' They found that at the nanometer scale, the electrons would be like a splash. The highest temperature is not at the maximum current, but it is in the direction of electron flow.
He vividly introduced that, 'For example, in computers and mobile phones, electrons have always been flowing, and the flow process generates a lot of heat. As the technology continues to advance, devices are getting smaller and smaller, and small chips consume so much. Electricity, the electrons inside will be getting hotter and hotter, which limits the size of the device. 'If you can use this discovery, redesign of integrated circuits, photovoltaic power generation and other components, is expected to greatly improve their performance, such as mobile phones 'Calls' will not be hot for ten hours or even 'strike'.
It is reported that this hot electron scientific research achievement is expected to increase the thermal management and energy efficiency of nanodevices in the future, making the chips smaller and smaller. It can also be used in the optoelectronics industry to substantially increase the photoelectric conversion efficiency of solar cells.
The research work was also funded by the National Natural Science Foundation of China, the National Key Research Program of the Ministry of Science and Technology of China, the major project of the Shanghai Science and Technology Commission, and the overseas scientists of the Chinese Academy of Sciences.
