WUHAN, China (February 28, 2023) - Wuhan Optoelectronics Forum No. 183 was successfully held in Auditorium C111 at Wuhan National Laboratory for Optoelectronics (WNLO) in the afternoon of February 28. Researcher Hailin Peng, Boya Distinguished Professor of Peking University, delivered an inspiring speech entitled "High-mobility 2D materials: Preparation and interface modulation". Prof. Jiang Tang, Deputy Director of WNLO chaired the forum and awarded Researcher Hailin Peng the forum medal.
Prof. Hailin Peng introduced that graphene can help achieve device miniaturization, then briefly introduced the technical requirements of high quality graphene single crystals for grain boundaries, folds and impurities, followed by the recent development of graphene in industry. The applications in electron microscope carrier net, high speed optical communication, and low power luminescence were highlighted.
In the second part of the report, Prof. Hailin Peng introduced the history of Bi2O2Se, a series of synthesis methods, material properties and its applications in heterojunction infrared detector, followed by some representative works of his group: epitaxial growth of Bi2O2Se, Bi2O2Se interface regulation to achieve ultra-thin dielectric layers, and two-dimensional vertical fin-layered materials. At the end of the report, Mr. Peng introduced his research route from single crystal to realized applications.
Prof. Hailin Peng is a Boya Distinguished Professor at Peking University. He graduated from Jilin University in 2000 and received doctor's degree in 2005 at Peking University. He has published more than 260 papers (including more than 30 articles in Science and Nature journals and their sub-journals), has been listed in the "Coreview" list of highly cited scholars, authored two monographs in Chinese and granted more than 60 patents. He has been awarded the National Outstanding Young Scholar Award, Young Innovator Award, Mao Yisheng Beijing Young Scientist Award, National Natural Science Second Prize, Ministry of Education Young Scientist Award, Science Discovery Award, etc. He is currently the Vice Dean of the School of Chemical and Molecular Engineering and the Vice President of Beijing Graphene Institute (BGI) at Peking University.
