Molecular Assemblies on Insulating Ultrathin Films Analyzed by NC-AFM and KPFM

Autor: Thilo Glatzel, Lars Zimmerli, Ernst Meyer

Publikováno v: Israel Journal of Chemistry. 48:107-116

Recently porphyrin-based molecules have proven to be promising candidates to form self-assembled structures oil insulating Surfaces. Their close similarity to hemoglobin and chlorophyll-based molecules makes them promising candidates for functional b

Publikováno v: Journal of Physics: Conference Series. 61:1357-1360

The formation of molecular wires on a nanostructured KBr(001) substrate is observed by non- contact atomic force microscopy. Locally polarized cyano porphyrin molecules evaporated on this sample assemble in a linear fashion along straight pit edges f

So far, most of the high resolution scanning probe microscopy studies of organic molecules were restricted to metallic substrates. Insulating substrates are mandatory when the molecules need to be electrically decoupled in a electronic circuit. In su

Functionalized truxenes : adsorption and diffusion of single molecules on the KBr(001) surface

Autor: T. Trevethan, Antonio M. Echavarren, Catelijne H. M. Amijs, Shigeki Kawai, Alexander L. Shluger, Ernst Meyer, Bartosz Such, Paula de Mendoza, Lars Zimmerli, Thilo Glatzel

In this work, we have studied the adsorption and diffusion of large functionalized organic molecules on an insulating ionic surface at room temperature using a noncontact atomic force microscope (NC-AFM) and theoretical modeling. Custom designed syn-

Publikováno v: Nanotechnology. 20:264016

In scanning probe techniques, accurate height measurements on heterogeneous surfaces are a major requirement. Different electrostatic potentials of various materials have a significant influence on the measured force/current and therefore a direct in
