PhD positions: Tailoring the Interaction in Heteroepitaxial Stacks of 2D Materials and Molecular Layers - Graphene, Hexagonal Boron-Nitride, Metal-Dichalcogenides and Molecular Films

Advertising institute: PGI-3 - Functional Nanostructures at Surfaces
Reference number: D100/2017, Physics, Chemistry

For its research towards molecule-based nanoelectronics and 2D materials, the department Functional Nanostructures at Surfaces (PGI-3) offers several PhD projects (Dr. rer. nat.) in the field of

Tailoring the Interaction in Heteroepitaxial Stacks of 2D Materials and Molecular Layers - Graphene, Hexagonal Boron-Nitride, Metal-Dichalcogenides and Molecular Films.

Internal interfaces are important for device functions in many contexts. Obviously, this is in particular true when 2D sheet materials like graphene (gr), hexagonal boron nitride (hBN), transition metal dichalcogenides (TMDC) or molecular layers are combined in layer-by-layer stacks. In the extreme limit, if each sheet of such a heteroepitaxial stack of 2D materials is a different material, a new class of bulk materials emerges that consists exclusively of internal interfaces (“the interfaces are the material”). We investigate the exceptional material properties of such systems in a systematic and comprehensive approach applying different complementary experimental techniques:

Electron Spectroscopy, (synchrotron-based) X-Ray Standing Waves, High Resolution Electron Energy Loss Spectroscopy, Low Energy Electron Microscopy, Scanning Electron Microscopy.
Further details about the actual research projects are available from the contact persons listed below.

All projects are funded by the Collaborative Research Centre 1083 “Structure and Dynamics of Internal Interfaces” (Sonderforschungsbereich 1083) of the University of Marburg and the strategic research initiative "Fundamentals of Future Information Technology" of the Helmholtz Gemeinschaft deutscher Forschungszentren, carried out by the Forschungszentrum Jülich (FZJ). The FZJ is one of the largest German research centres. It offers excellent opportunities for research in an international environment. Within the Jülich-Aachen Research Alliance (JARA), founded under the auspices of the German Excellence Initiative, it is closely linked to the RWTH Aachen University.
Salaries are competitive (TvöD + allowance depending on the candidate's profile), teaching load is low and dissertations are usually completed within three years. Equal opportunities are a cornerstone of our staff policy for which we have received the "TOTAL E-QUALITY" award.

Requirements
Candidates with an MSc or equivalent degree in Physics, Chemistry or a related discipline, with an overall grade of at least "good", are strongly encouraged to apply.

Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women. We also welcome applications from disabled persons.

Application
Further information about actual projects can be obtained from Prof. Dr. Christian Kumpf (c.kumpf@fz-juelich.de) and Dr. François Posseik (f.posseik@fz-juelich.de). Please send your application, including the relevant documents and stating your interests, to one of these contact persons, preferably via e-mail.
