We are a young and active team working on solid electrolytes at the Warsaw University of Technology. Our expertise is focused on the development of novel materials and devices based on polycrystalline materials. We are currently seeking a highly motivated and qualified individual for the position of Postdoctoral Researcher to work with us on ceramic lithium-ion conductors, especially on the interfaces in the multicomponent thin-film electrochemical systems. The successful candidate will have a strong background in research, focusing on the production of polycrystalline thin-film systems using PVD methods, particularly PLD and or thermal evaporation. The ideal candidate will also possess expertise in the characterization of physicochemical properties of thin-film systems, including structural analysis such as GIXRD and Raman spectroscopy, as well as electrochemical properties, including Electrochemical Impedance Spectroscopy.
