Abstract:
For a comprehensive understanding of complex semiconductor heterostructures and the physics of devices based on them, a systematic determination and correlation of the structural, chemical, electronic, and optical properties on a nanometer scale is essential. Luminescence techniques belong to the most sensitive, non-destructive methods of semiconductor research. The combination of luminescence spectroscopy – in particular at liquid He temperatures - with the high spatial resolution of a scanning transmission electron microscopy (STEM) as realized by the technique of low temperature cathodoluminescence microscopy in a STEM (STEM-CL), provides a unique, extremely powerful tool for the optical nano-characterization of quantum structures.

Brief CV of Prof. Frank Bertram:
Frank Bertram is working currently as a Professor at Otto-von-Guericke University in Magdeburg, Germany. His research focuses on the highly spatially resolved structural and optical characterisation of nanostructures, particularly nitride-based quantum structures. 

He completed his postdoctoral research at Arizona State University in the USA. He has also conducted research at the Institute of Multidisciplinary Research for Advanced Materials at Tohoku University in Sendai, Japan; the Institute of Materials Research and Engineering at the Agency for Science, Technology and Research in Singapore; and the School of Physics at Peking University in Beijing, China.

To date, he has published over 240 scientific papers and given more than 55 invited talks.
