附:报告人简介:
Nagarajan (Nagy) Valanoor received his B. Engg in Metallurgy from the University of Pune (1997) and Ph.D. from the University of Maryland (2001) under supervision of Prof. Ramesh in Materials Science and Engineering respectively. Following his Ph.D. he continued as a research associate at Maryland until 2003. He followed this with an Alexander von Humboldt Fellowship with Prof. Rainer Waser at Forschungszentrum Juliech. In 2005 he was offered a lec-tureship at the School of Materials Science and Engineering, where he is currently Professor and Research Director.
The main focus of Prof. Valanoor's research is interfaces in nanoscale functional oxides. Crucial to all modern electronic, magnetic and optoelectronic devices, interfaces are present wherever dissimilar materials meet. At interfaces (sometimes buried in the interior of solid samples) unique materials behavior can emerge and underpin a plethora of fundamentally new properties. Prof. Valanoor's central research contribution relates to designing artificial buried interfaces in complex oxide layers with atomic level control for nanoelectronic devices. At such interfaces, tailored atomic structures induce strong coupling between the mechanical, electrical, and magnetic properties, providing the ability to use electricity to affect mechanical properties or magnetics to affect electrical properties. Valanoor exploits this coupling to yield a new class of interface materials, several orders faster and with lower energy consumption, for technologies such as piezoelectric sensors and semiconductor logic transducers; paving the way for next-generation nanoelectronic devices. Prof. Valanoor is the author of over 150 articles with interface-themed research in functional nanomaterials. His h-index is 40 and career citations exceeds 7000.
