Postdoc position: High resolution TEM of 2D transition metal dichalcogenide nanolayers
We are looking for a talented and motivated Postdoc with a PhD degree in chemistry, (applied) physics, materials science or related field, with a strong background in transmission electron microscopy.
Two-dimensional transition metal dichalcogenides (2D-TMDs) are an exciting class of new materials. Their ultrathin body, optical band gap and unusual spin and valley polarization physics make them very promising candidates for a vast new range of (opto-)electronic applications.
So far, most experimental work on 2D-TMDs has been performed on exfoliated flakes made by the 'Scotch tape' technique. The major next challenge is the large-area synthesis of 2D-TMDs by a technique that ultimately can be used for commercial device fabrication.
The goal of this project is to use atomic layer deposition (ALD) to create a novel surface-controlled, industry-compatible synthesis technique that will make the synthesis of large area 2D-TMDs, 2D-TMD alloys and 2D-TMD heterostructures a reality.
In- and ex-situ analysistechniques such as high resolution TEM, FTIR spectroscopy, Raman spectroscopy and (non-linear) optical spectroscopy will be used to gain understanding in the surface chemistry involved in the ALD processes. Optical and electrical characterization will reveal the potential of the newly synthesized materials for (opto)-electronic applications.
This project is funded by the European Research Council (ERC Consolidator grant).
In this project there is currently one postdoc vacancy. This postdoc will use high resolution TEM to characterize 2D-TMDs, 2D-TMD alloys and 2D-TMD heterostructures grown by ALD, and study the growth mechanism of these nanomaterials systems. The postdoc will work in close collaboration with several PhD students who work on process development and optical and electronic characterization of the nanomaterials, and a theoretical postdoc who will perform atomistic simulations on the growth mechanisms. The postdoc may part-time be involved in the synthesis and optical and electrical characterization of the 2D materials as well, depending on the personal affinities of the postdoc.
The work will be carried out in the Plasma and Materials Processing group (PMP) at the Department of Applied Physics of Eindhoven University of Technology, the Netherlands. The group owns a JEOL ARM 200F TEM/STEM. The project is supervised by Dr. A. A. Bol and Dr. M. A. Verheijen.
We are looking for a talented and enthusiastic Postdoc with a PhD degree in (applied) physics, chemistry or material science or similar, with a strong background in surface science and crystallography. The ideal candidate is pro-active and independent and has proven experience with TEM of nanomaterials. Furthermore, the candidate has affinity with working in a multidisciplinary team and does not shy away from learning new deposition and characterization techniques. The Postdoc should also have good written and oral communication skills in English.
