Dr. Raphael Schlesinger’s dissertation released by Springer Theses

The dissertation of Dr. Raphael Schlesinger was selected to be published in Springer Theses, a dedicated book series to recognize outstanding doctoralresearch. Raphael’s work, conceived and performed within the CRC 951 at the physics department and IRIS Adlershof of Humboldt-Universität zu Berlin, was supervised by Prof. Norbert Koch, who is the deputy chairman of IRIS Adlershof. The thesis unravels fundamental mechanisms governing hybrid inorganic organic energy-level alignment and its purposeful manipulation.These insights pave the way towards new technological control and enable usage of hybrid materials and interfaces in future devices and applications.
IRIS Adlershof would like to congratulate Raphael Schlesinger and wishes him much success in his future work.

GLAD makes new organic memory devices possible

In the last news, (IOP Publishing) features an Nano Letters article by Giovanni Ligorio, Marco Vittorio Nardi, and Norbert Koch, who is a member of IRIS Adlershof:
"Researchers in Germany have used a technique called glancing angle deposition (GLAD) to fabricate non-volatile memory devices that are smaller than 100nm2. When integrated into the appropriate architectures, these devices have a memory density of more than 1 GB/cm2. They could be used in high-density, high-speed and low-power memories of the future."

Color Duality in Photons - an APS Highlight of the Year 2016

The paper “Ramsey Interference with Single Photons”[1] and accompanying Viewpoint “Photon Qubit is Made of Two Colors”[2] have been selected as one of the Highlights of the Year 2016 by APS Physics. It was co-authored by Dr. Sven Ramelow, who recently started his Emmy-Noether-Group at the Institute for Physics, Humboldt-University Berlin, and is associated with IRIS Adlershof. While there have numerous highly interesting papers in Physical Review Letters in 2016, APS Physics explains their selection, writing: “It’s no surprise that LIGO’s discovery of gravitational waves tops our list of favorite Physics stories in 2016. The other slots went to research that marked a change in perspective, demonstrated an impressive experimental feat, or simply made us think.”
Incidentally, Dr. Sven Ramelow is working on follow-up ideas and experiments of this paper, which he looks forward to soon being implemented at the HU Physics Department and at  IRIS Adlershof and yielding new intriguing results.
