信息科学技术学院近期计划邀请荷兰屯特大学Christian A. Nijhuis教授，面向全校师生做“Exciting Developments in Molecular Scale Electronics: From Molecular Switches to Neuromorphic Computing and Nanoscale Light-Sources”学术讲座。
报告人：Christian A. Nijhuis, University of Twente, Netherlands
Summary: Driven by the ever-increasing demand for miniaturized electronics, there is a drive to develop new types of energy-efficient multi-functional devices. Inspired by the efficiency of natural systems, think of our brains for computing or leaves to capture and convert solar energy, molecular systems are widely explored to develop new types of electronic devices. Electronic devices based on molecules operate via completely different mechanisms than traditional electronics based on silicon enabling new device functionalities that mimic the dynamical behavior of natural systems. I will introduce such molecular-scale devices that are based on individual molecules, or a monolayer of molecules, and explain briefly how they work. Next, I will give examples of new types of molecular switches where multiple electronic functions are preprogrammed inside a single molecular layer with a thickness of only 2 nm. Such switches contain dynamical behavior that mimics synaptic switching in our brains important for neuromorphic computing. Surprisingly, in the tunneling domain plasmon polaritons are excited; these junctions also function as nano-scale light sources. The talk will conclude with a brief perspective on exciting future directions.
Christian A. Nijhuis received his Ph.D. degree from University of Twente in 2006 (Cum Laude; top 5%). In the group of Professor George M. Whitesides, as a postdoctoral research fellow, he developed a platform for measurements of charge transport across layers that are one molecule thick. In 2010, he received the NRF research fellowship (3 million dollar) and he joined the Department of Chemistry at the National University of Singapore and was promoted to Assoc. Prof. in 2016. In 2012, he received the NRF CRP grant to start a new program to develop plasmonic-electronic devices which entered phase II in 2017 (total funding of 14 million dollar). In 2020, he moved back to the University of Twente as Full Professor to start a new group Hybrid Materials for Opto-Electronics. He co-authored >130 peer reviewer papers including Science, Nat. Mater., Nat. Nanotech., Nat. Photon., Nat. Chem., Nat. Comm., et al, gave >100 lectures at international meetings, received several awards (including Dean’s Chair (2018) and NUS University Young Researcher Award (2016)) and is member of several committees/boards (including Editorial Board member of iScience). His research interests cover the areas of molecular electronics, dynamical systems, plasmonic tunnel junctions, supramolecular chemistry, nanofabrication and surface science.
