Postdoc in Surface Physics, Dept. of Engineering and Physics

Description of Job As a Postdoc fellow, you will have the chance to conduct cutting-edge research in materials physics, taking advantage of state-of-the-art tools that will lead to attractive future job opportunities in academia or industry. Being part of this research project gives you the one-of-a-kind experience in form of doing experiments at the world´s first 4th generation synchrotron, MAX IV in Lund, Sweden. The successful candidate will contribute to the experimental and theoretical investigation of two-dimensional Pb films coupled to metal and semiconductor surfaces. This work builds on our ongoing, long-term research program centered on spin-split electronic structures of quantum wells—an area that has attracted significant attention in the context of spintronics. Complemented with density functional theory (DFT) calculations to build scientific and technical competence as well as strengthen transferrable skills, this position provides you with the skills, knowledge and competence needed to be successful in your field. Description of the workplace The Faculty of Health, Science and Technology invites applications for a post-doctoral fellowship in Physics at the Department of Engineering and Physics. Materials science is one of the faculty’s strategic research areas and has an inspiring multidisciplinary atmosphere. The materials physics group has a broad scope of interests encompassing research on metal/semiconductors, nano-materials, organic molecular and silicon-based solar cells, (see https://www.kau.se/en/physics/research/materials-physics ). The research on metal/semiconductor surfaces and interfaces is focused on surface structures; metal thin films, and organic crystalline layers, using experimental techniques such as scanning tunneling microscopy and synchrotron radiation methods such as angle-resolved photoelectron spectroscopy [1-3]. The materials physics group presently consists of seven senior scientists, two post-docs and seven PhD students, and is now growing strongly by the recruitments of more post-docs. References 1.
