The newly established Solid-State Materials Chemistry Group at the Laboratory of Inorganic Chemistry, Department of Chemistry and Applied Biosciences (D-CHAB), ETH Zurich, is seeking a highly motivated Doctoral Position.

Our research investigates how crystal chemistry, structure, and dimensionality can be used to control and create functionality in complex inorganic solids. We are currently establishing a laboratory for thin-film synthesis using physical vapor deposition methods, structural modification using wet-chemistry-based approaches, and advanced structural and functional characterization. Our long-term goal is to develop materials with potential for technology transfer to semiconductor and photonic industries, as well as energy conversion and storage applications.

Low-temperature chemical reactions (i.e., soft-chemistry) can drive topochemical transformations that modify the composition and structure of an existing solid while preserving its overall crystal framework. Layered perovskite oxides are particularly suited to this approach because their interlayer regions are chemically accessible, while the functional perovskite-derived slabs can remain intact. Changing the interlayer chemistry can alter crystal symmetry, give rise to charge discontinuities and structural distortions, providing a way to control functionality in solids, e.g. magnetic order, ferroelectric polarization configuration, electronic and ionic transport.

In this experimental Doctoral project, you will develop topochemical modifications of functional layered perovskites, working primarily with thin films and, where appropriate, single crystals and nanoparticles. Post-synthetic tuning, such as ion exchange, intercalation, redox reactions, will be used to access reversible property changes that are difficult to obtain by conventional high-temperature synthesis. The broader aim is to establish how topochemical transformations can reconfigure distinct electronic, magnetic, and dipolar states, enabling on-demand functionality for future memory, logic, and sensing applications.

• Preparing layered oxide precursors as thin films (pulsed-laser deposition), single crystals (e.g., floating zone method) or nanoparticles (e.g., hydrothermal synthesis)
• Developing post-growth topochemical reactions using solution-based and controlled-atmosphere methods
• Following changes in composition, structure, and functional properties using X-ray diffraction, Raman spectroscopy, scanning-probe microscopy, magnetometry, and electrical measurements, as well as experiments at large-scale facilities (e.g., Paul Scherrer Institute)
• Presenting your results at scientific conferences, publishing your work, and collaborating with researchers within the group and internationally

• You should hold a master’s degree in chemistry, materials science, physics or a related field and have a foundation in inorganic materials synthesis
• We are looking for a highly motivated, curious, and self-driven researcher who would be enthusiastic about helping establish a new laboratory: contributing to the installation of equipment, establishing safe and reproducible synthetic procedures, and helping create a collaborative group culture
• Excellent spoken and written English
• Willingness to work in an international and diverse team

Experience in one or more of the following areas would be advantageous, but not required: inorganic or solid-state synthesis, solution-based and soft-chemical methods, hydrothermal or solvothermal synthesis, thin-film deposition, single-crystal synthesis, scanning probe microscopy, electron microscopy, Raman spectroscopy, electrical transport measurements.

• A fully funded doctoral position for four years with a competitive salary according to ETH standards
• Access to a state-of-the-art ultra-high-vacuum thin-film deposition cluster, a laboratory for wet-chemical and solid-state synthesis, and advanced structural and functional characterization facilities
• Excellent training opportunities and employment conditions according to ETH Zurich standards
• You can expect numerous benefits, such as public transport season tickets and car sharing, a wide range of sports offered by the ASVZ, childcare and attractive pension benefits
• You will join a collaborative, inclusive, and intellectually stimulating research environment that values scientific curiosity, creativity, and independence

We look forward to receiving your online application with the following documents as a single PDF file:

• Cover letter (1 page) describing relevant skills and experience, research interests, and reasons for applying for the position
• CV, including qualifications and past academic and professional experience
• Academic transcripts for all university degrees
• Names and contact details of two referees (please inform them that they may be contacted)
• A representative example of your research work, if available, such as a peer-reviewed publication or thesis
