Description

A postdoc position in material science and physics is available at the department of Materials Science and Engineering (IMA). Based on Theoretical and Computational Modelling, the main task is to improve our understanding of modified 2D van-der-Waals materials for advanced bio-applications. 2D-hBN will be deposited by Pulsed Laser Deposition (PLD) technique and nanostructured using different highresolution physical approaches.

The exposure of 2D-hBN to either medium energy ions and charged clusters, or electron beam irradiation, under controlled conditions, will result in the formation of defects, inducing new functionalities and ways to nanostructure BN. The understanding of the physics underlying these new functionalities is critical to such applications. For this purpose, theoretical and computational studies will be performed.

Overall, our first-principles and interatomic potential based calculations will lead us to:

• Identify the thermodynamically favourable defects by computing defect formation energies under different growth conditions.
• Evaluate the stability of various defect configurations at different temperatures and check for possible defect healing, through molecular dynamic simulations.
• Examine the migration paths and energy barriers for moving defects using the nudge elastic band (NEB) method.
• Evaluate the impact of defects and impurities on the electronic properties by computing the electronic band structures. Projected density of states and partial charge densities will help us to identify the orbital character of the defect states. Especially for the cases where gap states will be observed, hybrid functional calculations will be additionally performed to obtain more accurate defect level positions with respect to the band edges.
• Evaluate the impact of defects and impurities on the transport properties by computing the electron effective masses.
• Evaluate the impact of defects on the optical properties by means of frequency dependent dielectric functions.
• Examine charged defects and charge transition levels
• Examine the charge transfer using the Bader population analysis.

Qualifications

The candidate should hold a PhD degree in physics or material science, have a strong background in solid state physics and atomistic simulations as well as with the aforementioned codes and scientific topics. The candidate should have high English language competence, and proven experience with manuscript preparation.
