PhD candidate in Group Organic Thin Films and Interfaces (m/f/d) in Jena At the Leibniz Institute of Photonics Technology ( Leibniz IPHT ) we are looking in the Research Department Quantum Detection for a full-time (100%) position for a PhD candidate (m/f/d) The position is to be filled as soon as possible and is initially limited to a period of 3 years. An extension will be sought if suitable. The Leibniz-IPHT is a university independent research institute with close connection to the Friedrich-Schiller-University Jena and member of the Leibniz association. Job description The work will be carried out within the framework of the Horizon Europe Marie Skłodowska-Curie Doctoral Training Network PhotoBrane ("Photo-tuning membranes for molecular separation"). PhotoBrane is at the forefront of innovation, developing next-generation photo-tunable and photo-regenerable membranes. These groundbreaking membranes potentially transform industries such as energy conversion, biomedical applications, water purification, and environmental protection by enhancing selectivity, permeability, and operational longevity. The proposed doctoral research project, titled “Fabrication, Development, and Characterization of Photo-Switchable Molecular Sieving Membranes”, will focus on light-responsive Langmuir layers. A range of amphiphilic molecular photo-switches will be utilized both in their pristine form and embedded within amphiphilic matrices. The process will be highly automated, incorporating dosing systems and a variety of in-line microscopy and spectroscopic characterization techniques, which will need to be designed and implemented within the project. Secondments to European partner institutions are mandatory. Your field of activity includes: Design and implementation of in-situ characterization techniques Fabrication and characterization of monomolecular membranes with systematically varied compositions, using Langmuir-Blodgett and related techniques JuPytR-based data analysis Your qualification: Master’s degree in physics Desired knowledge and skills: Prior experience in constructing optical systems and working in a chemistry laboratory Very good level of English (oral and written) Eligibility: Candidates can be of any nationality, but they must not have resided or carried out their main activity (work, studies, etc.) in Germany for more than 12 months in the 3 years immediately before the recruitment date. They must also be in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. We offer: An open welcoming culture and an inclusive and interdisciplinary working environment: Located on the Beutenberg campus in Jena, Leibniz-IPHT is home to more than 400 employees from around the world working at the interface of physics, biochemistry, technology, data science and medicine to develop the photonic technologies of tomorrow. World-class equipment and facilities : Leibniz-IPHT has a large number of physics, chemistry and biology laboratories at the highest level. It also has state-of-the-art fiber drawing and clean room facilities as well as microfluidics fabrication and big data computing facilities. Thorough and comprehensive personal training : Transferring good practices in scientific working and outreach is one of our main focus points. In a respectful and appreciative environment, you will learn everything you need for a career inside and outside of science. Moreover, plenty of workshops and opportunities for scientific exchange are offered by the Leibniz IPHT, as well as the Abbe School of Photonics and the Graduate Academy of the Friedrich-Schiller University Jena. A family-friendly working environment with support offers for the compatibility of family and work (e.g. parent-child office, campus kindergarten places, advice on family care situations from trained care guides and much more). Flexible working time models as well as 30 days vacation/year, special annual payment and bridge days. Jena - City of Science : a young city with a vibrant local cultural agenda Salary: Competitive salary as an EU researcher with full social benefits under European MSCA regulations.
