Infrared spectroscopy of Dirac semimetals under pressure

This PhD project will focus on the infrared spectroscopy of the exotic electronic states, which emerge under pressure and chemical doping in Dirac semimetals. Optical spectra will be examined in terms of the existence of Dirac fermions. Phase transitions to other states, such as Weyl semimetal, topological insulators, and topological superconductors will be traced. For details, please see the project description.

Examination of the chemical mechanism during thermal treatment of carbon fiber PAN precursors

By synthesis of isotopically labelled PAN precursors (2H, 15N, 13C) including their copolymers (with methylacrylate, itaconic acid?) and examination of the structural changes of them during thermal treatment by means of IR and NMR spectroscopy, DSC measurement and TG/GC/MS analysis the mechanism and elemental chemical reactions for the formation of efficient carbon fibers is worked out.
The knowledge about the detailed reaction pathways leading to most-efficient final carbon fiber material is still very limited. Thus, it is extremely difficult for carbon fiber producers (e. g. SGL Carbon) to systematically improve their products.
The chemically oriented work will include the synthesis and characterization of precursor polymers and copolymers and their thermal treatment as well as the synthesis and analysis of small model compounds.
