Research Statement

Our research interests are synthesis, integration and characterisation of low-dimensional nanomaterials with a particular focus on two-dimensional (2D) materials.

 

Using advanced in-situ and high-resolution materials characterisation techniques, we develop rational synthesis and integration protocols for carbon (graphene, carbon nanotubes) and related inorganic nanomaterials (hexagonal Boron-Nitride, transition metal dichalcogenides, pnictogens). Key techniques for nanomaterials synthesis are chemical vapour deposition (CVD) and, since recently, also liquid-phase-exfoliation (LPE). For materials characterisation we in particular employ a unique combination of spectroscopic and diffractive in-situ techniques during realistic synthesis and processing conditions (in-situ x-ray photoelectron spectroscopy (XPS) and x-ray diffractometry (XRD)) coupled with high-resolution (scanning) transmission electron microscopy ((S)TEM).

We thereby aim to facilitate industrially-scalable, controlled growth of low-dimensional nanomaterials and enable their controlled device integration with other functional materials such as metals, metal-oxides and organics. This contributes to realisation of a wide range of nanomaterials applications including low-cost, transparent, flexible electronics, efficient low-cost energy harvesting/storage/conversion devices and ultrathin functional coatings of structural materials.

Team and Principal Investigator (PI)

For an overview of present and alumni team members please see our Team and PI page.

Our research efforts are led by junior research group leader Dr. Bernhard C. Bayer. After a PhD and a College Research Fellowship at the University of Cambridge, UK and a Marie-Sklodowska-Curie-Fellowship at the University of Vienna, Austria, Dr. Bayer joined TU Wien’s Institute of Materials Chemistry to build up the Nanomaterials Synthesis and Integration junior research group. For more information on Dr. Bayer’s CV see the Team and PI page.

Join us!

We are continuously seeking interns, Bachelor, Master and PhD candidates, with backgrounds in Chemistry, Materials Science, Physics and Engineering.

At all levels we aim for rewarding learning-through-research projects with exposure to a wide range of synthesis and complementary characterisation techniques as well as application performance screening of the newly synthesised materials. From undergraduate level onwards it is key for us that every new team member’s work is contributing to the forefront of nanomaterials research, thus often resulting in published work even from shorter internships or Bachelor theses (recent example: Nicole Rosza’s Bachelor work contributing to https://arxiv.org/abs/2105.09885).

Currently we have in particular plenty of interesting opportunities for Master and Bachelor theses. Please do not hesitate to get in touch (bernhard.bayer-skoff@tuwien.ac.at)!
