Lars Samuelson obtained his Ph.D. in Solid State Physics at Lund University in 1977. After a post-doc at IBM Research Labs in San José, CA, he returned to Lund in 1979. In 1986 he became Professor in Semiconductor Physics in Göteborg and returned to be Professor at the Physics Department in Lund in 1988. He is director of the Nanometer Structure Consortium, started in 1988, and today the primary center for Nanoscience in Sweden. He is the scientific leader of a Strategic Research Center “Nanowires for emerging nanoelectronics and life-science applications”, and of a major European R&D Integrated Project called NODE, “Nanowire-based One-Dimensional Electronics”. LS is internationally recognized for his research on low-dimensional structures and the physics and applications made possible by these structures. In recent years his research has been directed towards new ways for the formation of ideal one-dimensional nanowires through self-assembly, studies of their physical properties, as well as applications of semiconductor nanowires in electronics, photonics and the life-sciences. He has published about 450 papers in refereed journals and given about 200 invited/plenary talks at international conferences (h-index=49). In 2005, the research program on NANOWIRES directed by LS, was selected by the Swedish Research Council as one of 10 top research environments among all areas of science in Sweden. In 2008 he was awarded as “Einstein Professor” by the Chinese Academy of Sciences. He is Fellow of the Institute of Physics, FinstP, in the United Kingdom, Fellow of the American Physical Society, a Member of the Royal Swedish Academy of Sciences, KVA and of the Royal Swedish Academy of Engineering Sciences, IVA.
