We are interested in two -partly overlapping- fields. Firstly, we study the physics of 2D correlated electron systems at surfaces. The spatial accessibility of surface systems allows for a detailed spatial resolved study of the role of disorder on the electronic properties of strongly correlated low dimensional systems. Secondly, the process of self-organization of ordered one- or two-dimensional structures at surfaces and the role played by intrinsic disorder or structural fluctuations in these self-assembled structures. We mainly use established surface analytical tools such as Scanning Tunneling Microscopy and Spectroscopy (STM and STS) both at room temperature and low temperatures. We also use LEED and surface conductivity measurements, and we hope to do Angle Resolved Photoemission Spectroscopy. |
