Molecular engineering of low-dimensional materials exploiting controlled self-assembly and positioning of individual atoms or molecules at surfaces opens up new pathways to control matter at the nanoscale. Our research thus focuses on the study of functional molecules and supramolecular architectures on metal substrates. As principal experimental tools we employ low-temperature scanning tunnelling microscopy and spectroscopy. Here we review recent studies in our lab at UBC: Controlled

Lausanne. His research focuses on nanoscale science on surfaces, specifically addressing the geometric and electronic structure of molecular buildings blocks and their self-assembly into supramolecular architectures. Agustin Schiffrin is a PhD student in Chemistry at the University of British Columbia since 2004. His doctoral research project focuses on the self-assembly of biologically relevant molecules on noble metal surfaces and their characterisation with scanning tunnelling microscopy and complementary X-ray absorption surface science techniques. In 2003, he obtained a Diploma in Physics from the Ecole Polytechnique Fédérale de Lausanne. Alexander Weber-Bargioni completed his PhD in Physics at the University of British Columbia in 2007. His doctoral research focused on the investigation of porphyrin molecules absorbed on metal surfaces. By means of scanning tunnelling microscopy/spectroscopy he studied their self-assembly to supramolecular nanostructures and their electronic structure on the single molecule scale. He is currently at the Lawrence Berkeley National Laboratories, where he investigates the interaction of light with single molecules. He has an MSc from The University of British Columbia, an MSc from the Portland State University and a Vordiplom/BSc from the University of Konstanz, Germany. Yan Pennec is a research associate in the Physics and Astronomy Department at the University of British Columbia. After the obtainment of his PhD on the Magnetisation Dynamics of Ultra-Thin Films at the University Joseph Fourier in France, he focused during post-doctoral appointments on the studies of surface science at the University of Alberta and later on at the University of British Columbia. He used the scanning tunnelling microscope as a tool of choice for the investigation of condensed matter down to the atomic scale. His interest covers a large range of topics from semiconductors to oxides to organic materials. Molecular nanoscience and engineering on surfaces 1173 Andreas Riemann is an Assistant Professor at Western Washington University. He previously was a postdoctoral fellow at the University of British Columbia. His postdoctoral research focused on molecular nanostructures on metallic substrates investigated by low-temperature STM. Currently, he is studying functional molecules under ambient conditions with STM and also magnetic multilayer structures using LEED and MOKE. He has a PhD from the Freie Universität Berlin and a Diploma from the Martin-Luther-Universität Halle Wittenberg. J.V. Barth is presently Adjunct Professor at
