Inorganic Materials Chemistry

From Precursor Synthesis to Advanced Materials



Second confirmation: New Project No.2

The DFG grants funding of a PhD project focused on " Synthesis and Transport Phenomena of Nanocale, Metastable Solid Solutions and the Formation of Functional Heterostructures".
The research consortium includes M. Sistani (TU Wien) and M. Huth (Goethe University Frankfurt) who will also work on the topic in the frame of our joint DACH project. More details will be shared in the near future.

In case you are interested in working on either topic as a PhD student, please contact S. Barth via email.


First Domino has fallen: New Project

The DFG will fund a PhD  project focused on "Site-Selective Growth and Characterization of Nanocale Superconductors". We will distribute the call for applications soon.

New Review on precursors in FEBID Processes

In this collaboration with Michael Huth, we are trying to bridge the more chemical oriented experiments reported in literature with the actual FEBID process in order to entangle the complex process on the surface. This overview should provide a didactive introduction in the field and some inspiration for the design of new precursors, while being supportive to practitioners in the field. The paper is entitled "Precursors for Direct-Write Nanofabrication with Electrons" and will be published in the Journal of Materials Chemistry C. The review can be downloaded here.
