Introduction
The research of my PhD is based on the synthesis and characterization of novel heteroanionic compounds (2D-chalcohalides). I am particularly interested in compounds that exhibit heteroleptic coordination. To synthesise these materials, I use solid-state reactions and chemical vapour transport (CVT).
Furthermore, I have worked in the past on the synthesis of alpha-ruthenium trichloride and on the conceptual design of an electrochemical 2.5D printing process.

The rapidly growing interest in synthesising 2D Janus materials is supported by the numerous theoretical predictions of the unique properties of this material category. Here, we report the discovery of the novel 2D Janus material RhSeCl which crystallises in a space lattice with hexagonal symmetry P63mc with the unit cell parameters a = 3.48760(10)...
Many of the solid-state materials needed for today's technologies are based on homoanionic compounds, e.g. chalcogenides or halides. In recent years, far-reaching modifications of these compounds were achieved only by varying the cations, while the influence of exchanged anions, in particular the combination of different anions, has seldom been inv...
The honeycomb Kitaev-Heisenberg model is a source of a quantum spin liquid with Majorana fermions and gauge flux excitations as fractional quasiparticles. Here we unveil the highly unusual low-temperature heat conductivity κ of α−RuCl3, a prime candidate for realizing such physics: beyond a magnetic field of Bc≈7.5 T, κ increases by about one order...
A quantum spin-liquid might be realized in $\alpha$-RuCl$_{3}$, a honeycomb-lattice magnetic material with substantial spin-orbit coupling. Moreover, $\alpha$-RuCl$_{3}$ is a Mott insulator, which implies the possibility that novel exotic phases occur upon doping. Here, we study the electronic structure of this material when intercalated with potas...

Kitaev-type interactions between neighbouring magnetic moments emerge in the honeycomb material ${\alpha}$-RuCl3. It is debated however whether these Kitaev interactions are ferromagnetic or antiferromagnetic. With electron energy loss spectroscopy (EELS) we study the lowest excitation across the Mott-Hubbard gap, which involves a d4 triplet in the...
The honeycomb Kitaev-Heisenberg model is a source of a quantum spin liquid with Majorana fermions and gauge flux excitations as fractional quasiparticles. In the quest of finding a pertinent material, $\alpha$-RuCl$_{3}$ recently emerged as a prime candidate. Here we unveil highly unusual low-temperature heat conductivity $\kappa$ of $\alpha$-RuCl$...
Novel ground states might be realized in honeycomb lattices with strong spin-orbit coupling. Here we study the electronic structure of α−RuCl3, in which the Ru ions are in a d5 configuration and form a honeycomb lattice, by angle-resolved photoemission, x-ray photoemission, and electron energy loss spectroscopy supported by density functional theor...

Synthesis and characterization of novel materials with two different monoatomic anions in a mutal lattice.
Project B01 within the CRC 1143 programme "Correlated magnetism: from frustration to topology" offers a full-time PhD position in materials chemistry / solid-state physics. The project may start from January 2019 and has a fixed duration of 3 years. Further information about the CRC and the positions can be found here: https://www.verw.tu-dresden.de/stellaus/download.asp?file=12-2018%5CVojta_12WIMI_eng_191018_516.pdf

The B01 project in particular explores materials aspects of oxide and halide frustrated magnets based on 3d, 4d, and 5d transition metals with three central aims: (i) development of synthetic routes for polycrystalline samples of emergent frustrated magnets, (ii) exploration of growth routes for yet unavailable single-crystals, and (iii) investigation of structural, magnetic and thermodynamic properties of magnetically frustrated materials. Classes of materials that will be studied comprise double perovskites with anisotropic or competing magnetic interactions; layered cluster compounds with kagome structural motifs; layered trihalides as well as layered oxyhalides and tetrahalides.
