Zhang Zhiyong's team from the School of Electronics has made important progress in the field of paper-based carbon nanotube CMOS transistors and integrated circuits

In recent years, with the rise of the concept of the Internet of Things, electronic products continue to develop in the direction of thinness, flexibility, functionality and ultra-low power consumption, paper-based electronic technology and special functional electronic circuits have come into being

Recently, the Zhang Zhiyong Research Group of Peking University cooperated with the Zhao Jianwen Research Group of the Suzhou Institute of Nanotechnology of the Chinese Academy of Sciences to prepare carbon nanotube thin film transistors on a paper substrate by using the advantages of high carbon nanotube switching ratio, good chemical stability, high mechanical strength, and quasi-one-dimensional structure
