物理学与信息技术学院 恒元物理学讲座（第047期）：Road Beyond CMOS

讲座内容： For past 50 years, charge based silicon technology and scaling law (Moore’s Law) have been the fundamental driver of computational technology, catalyst for the emergence of the Digital Age. In this “no trade-off” era, consistent exponential performance growth is sustained by vigorous feature scaling, while computation is kept utilizing the Boolean logic and Von Neumann architecture system, achieving exact calculation and communication gain through noise suppression. However, as the technology node reaches beyond 10nm, the complexity of Si-based transistor has increased tremendously and become cost-prohibitive, new functional material needs to be developed. All industry-developed countries and world major semiconductor companies are actively searching for the next “Genome” material to replace Si. Currently, the low dimensional physical material system like Graphene, MX2, topological insulator, ultra-thin spintronic thin film system are being eagerly explored as candidates which promises many revolutionary ways of future computing.
