Properties of Quasi-1D and Quasi-0D Systems

Michael Springborg - University of Saarland, Physical and Theoretical Chemistry

Also because of quantum-confinement effects, systems that are finite in one or more dimensions possess properties different from those of extended, 3-dimensional systems. To study, understand, and exploit these properties is, therefore, highly relevant both for fundamental sciences and for applications. However, the combination of finite extension in some dimensions and (approximately) infinite extension in the others is a challenge for theoretical studies.

In this set of lectures, the foundations for theoretical studies of electronic and structural properties of materials shall be briefly summarized.

Subsequently, these methods shall be applied to the study of polymers and chain compounds as examples of quasi-1D systems and to clusters and collids as examples of quasi-0D systems.

Special emphasis will be put on extracting information that can be used in obtaining a general understanding of the materials properties.
