International WE-Heraeus Physics School: Exciting Nanostructures: Probing and Tuning the Electronic Properties of Confined Systems

Physikzentrum Bad Honnef, Germany
Veranstaltung von 17 Jul 2017 bis 21 Jul 2017

Scientific organizers: PD Dr. C. Klinke, U Hamburg • Prof. N. Gaponik, TU Dresden




The developments in our society in terms of computing power, sensing, and alternative energy demand new generations of building blocks for future optical and electrical applications with higher efficiencies and lower costs. In the recent years enormous progress has been made in defining nanostructures and in understanding their physical properties. Nowadays, it is possible not only to prepare spherical, zero-dimensional nanoparticles, but also one-dimensional nanorods, two-dimensional nanosheets and hybrid materials. Shape and structure have a strong influence on their physical properties which results mainly from their large surface-to-volume ratio and/or from the quantum confinement of their electrons and holes – but also plasmonic effects play a big role. The development of such materials has led to a broad range and ever increasing number of electronic applications amongst which are LEDs both for lighting and for displays, batteries and capacitors, highly selective catalysts and electrocatalysts, sensors and photodetectors, and many more. Scientifically, low-dimensional objects also represent exceptionally interesting model systems which allow the extension of classical and the development of alternative concepts on a new field of physics with ground-breaking insights. Examples are single-electron transistors, Coulomb blockade, ballistic transport over micrometers in length, and continuously tunable optical properties. In order to produce nanomaterials with new, tailored properties it is indispensable to understand the synthesis mechanisms in detail.

In this summer school the basics of the preparation of nanostructures, the resulting physical properties, their electronic applications, and theoretical methods will be reviewed. A range of characterization techniques with a special emphasis on spectroscopy will be introduced. The summer school provides an ideal forum for Master and PhD students to become acquainted with the topic and to initiate further discussions.
