Aarhus University
The Goesten Group at the Department of Chemistry, Aarhus University, is seeking a candidate for a 12 months fulltime postdoctoral position, co-supervised by Prof. Yong Chen and Prof. Jill Miwa at the Department of Physics. The position is available from the 1st of May 2026, or as soon as possible hereafter. Job description Your research will look at a special class of porous metal-organic frameworks (MOFs) that is based on redox-active organic building blocks. These building blocks enforce charge delocalization and give rise to exotic quantum states that relate to superconductivity. This project will focus on two types of phenomena: (i) Charge Density Wave (CDW) order in magnetic, lanthanide-based MOFs and (ii) electride-like, quasiatomic electron states that reside in the pores of certain MOFs. The aim of the project is to map these states with Scanning Tunneling Microscopy/Spectroscopy (STM/STS) and where possible, angle-resolved photoemission spectroscopy (ARPES). Your work will focus on the spectroscopy, and does not involve single-crystal synthesis. This project involves intensive international collaboration with multiple research groups. Your profile You hold a PhD in physics, chemistry or materials science. Preferably you have a background in STM/STS, photoelectron spectroscopy (ARPES, XPS) or Atomic Force Microscopy (AFM). Preferably you have experience with Ultra High Vacuum sample preparation, cryogenics and surface-science tools. You have strong communication and writing skills in English. You are a team player but also do not mind working independently. Who we are/ The Department The Department of Chemistry at Aarhus University (www.chem.au.dk) is one of the leading European chemistry departments with a broad research programs. It has a permanent staff of 35 full and associate professors, a support-staff of 30 people, 150 PhD-students and postdocs and around 400 students.
