In this summer school, the basics of the preparation of nanostructures, the resulting physical properties, their optoelectronic 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. The participants are expected to present their own work in the form of posters and are given the chance to introduce it also in the form of flash presentations (2 min talk with 1 slide). Leading experts in nanostructure preparation, spectroscopy, electrical transport and related fields will be invited as speakers.

First virtual conference on solution-based optoelectronic nanomaterials

Thursday April 30, 2020, 3 pm to 7 pm CEST (Central European Summer Time)

Organized by Christian Klinke


Solution synthesized and processable nanostructures become increasingly important. The materials are intriguing from a fundamental point of view with many potential insights in terms of chemical synthesis and physical characterization, but also real-world applications appear at the horizon. Their extraordinary electronic, phononic, optical and mechanical properties make them promising materials for a myriad of applications (spintronic devices, field-effect transistors, nanoscale sensors, batteries, inexpensive photodetectors, LEDs, and lasers). This virtual conference is a new approach to bring together the multidisciplinary scientific community working on the synthesis, the physics and applications in devices. Keynote speakers are Prof. Horst Weller from the University of Hamburg and Prof. David Norris from the ETH Zurich.
