research assistant (Praedoc)
with 66%-part-time job
limited to 30.09.2021 (end of project)
Entgeltgruppe 13 TV-L FU
reference code: JOSPEC

The local competition of the superconducting ground state with a nanoscale exchange or Coulomb potential opens an extremely rich field of physics, including Shiba or novel Majorana-type states. We are investigating the underlying physical principles using low-temperature scanning tunneling microscopy and spectroscopy. We have gained important insights from conventional tunneling spectroscopy with superconducting tips. Our group is now developing new spectroscopic methods to investigate these systems by Josephson tunneling and high-frequency excitations.

Job description:

You will participate in a collaborative project between the group of Katharina Franke in Berlin and Clemens Winkelmann in Grenoble. The main experimental work will be carried out in Berlin, but some visits to the group in Grenoble are planned. You will be working on a low-temperature scanning tunneling microscope, performing high-resolution conventional tunneling spectroscopy and Josephson spectroscopy. You will also couple high-frequency radiation into the Josephson junction and measure its response. You will investigate single magnetic atoms on superconductors as well as grow magnetic nanostructures. You will be working in a small team and act as a strong link between the group in Berlin and Grenoble. You are given the opportunity to undertake doctoral research.

Requirements:

Master of Science in Physics.

Desirable:

Experience in the following areas: scanning tunneling microscopy/spectroscopy, surface physics, ultra-high vacuum techniques, low temperature equipment, superconductivity, high-frequency techniques.

All applications quoting the reference code should be addressed no later than September 10th, 2018 to Frau Prof. Dr. Katharina Franke: franke@physik.fu-berlin.de or by post to

research assistant
with 3/4-part-time job
limited to 4 years
Entgeltgruppe 13 TV-L FU
Kennung: PhD Nano Science

Job description:

We seek to fill a PhD (4 years) position in nanomaterials synthesis and characterization. The interdisciplinary research will focus on novel hybrids based on carbon nanotubes and graphene. The successful candidate will create optoelectronic hybrids from nanotubes and graphene by functionalizing them with molecules and inorganic nanostructures. The functionalization will follow the covalent synthetic route specifically developed by us to preserve fully the conjugated nature of the nanotubes. The hybrids will be investigated by optical spectroscopy and Raman scattering to demonstrate their optical functionality. Collaborations with groups working on electronic transport of nanoscale systems will allow studying the electronic response. The systematic investigation of the effect of the synthesis parameters onto the physical features of the hybrids will be an important part of this work. Synthetic as well as analytical skills are highly relevant.
We are looking for candidates able to perform complex functionalization and physically characterize nanomaterials through various techniques (optical and electron microscopy, atomic force microscopy, linear and nonlinear spectroscopy).

Requirements:

MSc in Chemistry, Material Science, Physics, or a related field. Academic excellence. We will evaluate applications from various subfields. Highly desired is proven experience in one or more of the following areas: Synthetic chemistry, physical chemistry, science and chemistry of carbon-based nanomaterials, optical and Raman spectroscopy on nanostructures

Further details on the position are available from Prof. Stephanie Reich (reich@physik.fu-berlin.de).

Applications with a cover letter, CV, list of publications, and the names of two references should be sent no later than September 14th, 2018 to Prof. Stephanie Reich at appl-gmn@physik.fu-berlin.de or to
