Education Stefan Heun received his diploma in physics in 1989 from the University of Hannover, where he investigated in the group of Prof. M. Henzler the initial stages of epitaxial growth of silicon on Si(100) [download diploma thesis]. In 1993 he received his Ph.D. in the same group, working on the magnetoconductivity of monolayer-thin films of Ag, Pb, and Au deposited on Si(111) [download Ph. D. thesis]. Research Activity In 1993 he joined the Interdisciplinary Research Laboratories of the Japanese Telecom NTT in Tokyo, where he studied the surface passivation of III-V semiconductors using synchrotron radiation. In 1995 he moved as a TMR Marie Curie research fellow of the Commission of the European Community to the Materials Division of the TASC lab in Trieste, where he worked on the engineering of heterostructure interfaces. In 1997 he became a beam line scientist at the Sincrotrone Trieste, where he was appointed responsible of the Nanospectroscopy Beamline, at which he also performed his research on the properties of low-dimensional systems. Finally, in 2004 joined the INFM- CNR as a senior scientist, first at the TASC in Trieste and since October 2006 at the NEST in Pisa. In these last years his main research interest is the use of low-temperature scanning probe microscopy for the spectroscopic study of semiconductor nanostructures. Research Summary His main research interest is the physics of low-dimensional systems. This includes three aspects: (i) the synthesis of nanostructures, (ii) the manipulation of samples on the nanometer-scale, and (iii) their characterization with spatially resolved spectroscopic techniques. Stefan Heun has co-authored more than 110 journal papers and has given more than 90 presentations at conferences and international institutes. Graduate Advising 1991 - 1992: J.
