      abstract     = {The main subject of this work is to describe the design,
                      preparation and understanding of a conductive sensor and to
                      verify its functionality in order to asses different states
                      of the molecular deposition during the preparation of
                      self-assembling organic molecule monolayers by in-situ
                      determining their electronic conductivity. In the first part
                      of this thesis the working principle of the conductive
                      sensor which is based on the different types of conductivity
                      (e.g. ionic, electric, displacement current, defect
                      conductance) and binding capabilities of the molecules were
                      introduced. In the second part the construction steps of a
                      conductive sensor is sketched followed by verification of
                      its functionality demonstrated for two different molecules,
                      (3-Aminopropyl) triethoxysilane(APTES) and
                      (3-Glycidyloxypropyl) triethoxysilane (GLYMO). Both
                      molecules have already been analyzed with a corresponding
                      capacitive sensor and the results of the two sensors are
                      compared. Additionally, the presence of molecules on the
                      substrates is confirmed by ex-situ analysis, e.g. optical
                      microscope, atomic force microscope (AFM), ellipsometry,
                      X-ray photoelectron spectroscopy (XPS) and wetting angle
                      measurements. In the following experimental part, first both
                      molecules, APTES and GLYMO, are analyzed in the liquid state
                      in order to obtain an electronic reference for the
                      interpretation of the data of the conductive sensor. Then
                      the in-situ monitoring of the growth of organic molecular
                      layers is demonstrated using the conductive sensor that was
                      developed in this work. The data obtained for APTES, GLYMO
                      and Cysteamine (CYS) are interpreted in the framework of
                      existing models combining the experimental data, using the
                      knowledge gained from the experiment of the molecules in the
                      liquid state and ex-situ analysis of the grown films. The
                      conclusion of this thesis is that the conductive sensor
                      allows a detailed look into the different steps and states
                      of the molecular deposition and, thus, represents an ideal
                      tool for a controlled molecular layer deposition (MLD) of
                      organic molecules suitable for applications.},
