Numerical calculations for electronic transport through molecular systems
… Meilenstein setzte auf diesem Gebiet die Rastertunnelmikroskopie, welche ursprünglich für die Abbildung von Oberflächen mit atomarer Auflösung entwickelt wurde (Binnig et al., 1981). Heute ermöglicht sie die gezielte Untersuchung von Transporteigenschaften einzelner, auf Oberflächen …

Design of a low-temperature scanning tunneling microscope system used to examine graphene nanomembranes
This thesis describes the design and assembly of a low-temperature UHV-system including a scanning tunneling microscope. It operates at a temperature of 5 K and at a base pressure of 10^-8 Pa. Using this microscope, I have examined the mechanical behavior of graphene nanomembranes under the …

Charakterisierung des Ladungstransfers von immobilisiertem Cytochrom c
The Aim of this work was to study the charge transfer of redoxactive proteinswith new techniques. Especially the behavior of individual proteins should be observed to obtain a clear and deep insight in the charge transfer and its influencing parameters. Since methods that integrate over a large …

Bi surfactant mediated growth for fabrication of Si,Ge nanostructures and investigation of Si,Ge intermixing by STM
Heteroepitaxial growth of Ge on Si is a prototypical system for studying strained Stranski-Krastanow growth.The technological drawback is that it turns out to be difficult to grow Ge on Si in a controlled layer-by-layer manner. After a few smooth layers have been grown epitaxially, the growth then …

Investigation of a metal-organic interface - realization and understanding of a molecular switch
The field of molecular organic electronics is an emerging and very dynamic area. The continued trend to miniaturisation, combined with increasing complexity and cost of production in conventional semiconductor electronics, forces companies to turn their attention to alternatives that promise the …
