Studierende finden an der ETH Zürich ein Umfeld, das eigenständiges Denken fördert, Forschende ein Klima, das zu Spitzenleistungen inspiriert.
This is a joint position between Functional Inorganic Materials Group (, ETH Zurich) and Laboratory for Transport at Nanoscale Interfaces (, Empa, Dübendorf)
The research activities in FIMG are focused on challenges related to the chemistry, physics, and applications of inorganic materials ranging from nanostructures to powders, thin films, and single crystals. Central to our efforts is the synthesis of inorganic materials and their integration or self-assembly into multifunctional solid-state structures. Synthetic work and rigorous materials characterization are the cornerstones of our research.
LTNI focuses on the fabrication of the atomically-precise nanostructures and low-dimensional materials and investigation of their fundamental electronic, optoelectronic, thermal, and ionic transport properties. The group has a broad expertise in heterogeneous integration of novel nanomaterials by custom-made methods for nanoscale patterning and interfaces nanostructuring.
This project aims at the development of colloidal nanocrystals for thermoelectric application. Central to the project will be the chemical synthesis of nanocrystals, tailoring and characterization of their surface chemistry, followed by their assembly into densely packed solids. Hot-injection techniques will be used to synthesize colloidal nanocrystals with the main focus on near-IR-active materials (e.g., PbS) but also including lead halide perovskites. Exploration of various ligands (halides and chalcogenides) and ligand exchange techniques (solution-processed and solid-state) will be a core part of the project. One of the goals is to produce superlattices of electronically-coupled nanocrystals. Another part of the project will include characterization of electronic and thermal properties of these superlattices (thermal and electrical conductivities and Seebeck coefficient).
The research activities will involve:
The preferred start is in the fall of 2020 or upon agreement.
