Molecular NanoscienceThe focus of the group is the investigation of various molecules (or nanostructures) on surfaces. Diverse mechanical, magnetic, and electronic properties are studied using surface sensitive techniques: X-ray Photoelectron Spectroscopy (XPS), Scanning Probe Microscopy (SPM), X-ray Magnetic Circular Dichroism (XMCD) spectroscopy, Low-Energy Electron Diffraction (LEED) and others.
Currently our main interest is concentrated at controlling spins in adsorbed molecules by chemical and/or physical switches. We perform in-depth studies of various molecule-switch combinations in order to understand the mechanisms ruling the magnetic response. Density Functional Theory (DFT)+U calculations performed by our collaborators (see below) give a very important input to achieve this goal.
