The Institute of Ion Beam Physics and Materials Research invites applications as

PhD Student (m/f) in "Atomistic simulations of two-dimensional materials encapsulated between graphene sheets"

The position will be available from 1 October 2017. The employment contract is limited to three years. The regular weekly working time will be 19,5 hours. The salary is based on the collective agreement TVöD-Bund. The place of work is Dresden-Rossendorf.

Requirements:

  • Master degree in solid-state physics, computational physics or materials science with very good marks
  • good scripting and programming skills
  • experience with atomistic simulations (molecular dynamics, density functional theory calculations)
  • excellent written and oral communication skills in English
  • readiness to work in an international team and closely collaborate with experimentalists

Tasks:

  • carry out density-functional-theory and analytical potential molecular dynamics simulations aimed at understanding the electronic and mechanical properlies of 2D materials encapsulated between graphene sheets
  • assess structural transformations in such systems induced by the electron beam in high-resolution transmission electron microscope
  • closely collaborate with the experimental group of Prof. Ute Kaiser, University of Ulm, involved in the project
  • develop the dedicate software for the analysis and interpretation of the evolution of 2D materials encapsulated between graphene sheets under electron beam

Project Description:

2D inorganic materials have unique electronic and optical properties, but many systems are unstable in air. A possible solution is to encapsulate them between graphene or BN sheets, which are chemically inert. Moreover, such an approach makes it possible to create new materials with reduced dimensionalities. In the project “Imaging and atomic structure engineering of quasi-two-dimensional materials encapsulated between graphene sheets” (Principal Investigators Ute Kaiser, University of Ulm, and Arkady Krasheninnikov, HZDR) funded by DFG, we are going to study such systems and their transformations under electron beam by combining high-resolution transmission electron microscopy (to be performed at University of Ulm, https://www.uni-ulm.de/einrichtungen/hrem/) with atomistic simulations. The project will give a unique opportunity to carry out a theoretical research in a ‘hot’ area in close collaboration with one of the world-leading experimental groups focused on the electron microscopy of low-dimensional systems. The groups have successfully worked together with many joint papers in high-impact journals, and it is expected that many  important results will be obtained, which would enable one to explore promising avenues for engineering the structure and properties of novel encapsulated nanostructures.

If you have any questions, please contact Dr. Arkady Krasheninnikov, Tel.: +49 351 260 - 3148 or Dr. Stefan Facsko, Tel.: +49 351 260 - 2987.

Kindly submit your completed application (including cover letter, CV, diplomas/transcripts, etc.) by 31 July 2017 only via Online application (English / German).

The HZDR is committed to equal opportunity employment and we strongly encourage applications from qualified female candidates. We also carefully consider all applications from job candidates with severe disabilities.
