      abstract     = {This thesis presents a novel method for studying capillary
                      imbibition and vapor sorption in mesoporous silicon (PSi)
                      with white light spectroscopy. By
                      Fast-Fourier-Transformation of thin film interference and
                      parallel analysis of an optical microcavity within the
                      porous layer, it achieves high precision in monitoring fluid
                      dynamics. The research includes a constriction model for
                      capillary imbibition, the resolution of liquid menisci and a
                      percolation mechanism for vapor sorption. Moreover, a new
                      rapid and non-destructive technique is introduced for
                      assessing pore pathways of PSi, by calulating the pore
                      geometry from liquid dynamics and capillary pressure.Diese

                      Silizium (PSi) mit Weißlichtspektroskopie vor. Durch die
                      Fast-Fourier-Transformation von Dünnschichtinterferenz und
                      parallele Analyse einer optischen Mikrokavität wird eine
                      hohe Präzision bei der Messung der Fluiddynamik erreicht.
                      Die Forschung umfasst ein Flaschenhalsmodell für die
                      kapillare Imbibition, die Auflösung von
                      Flüssigkeitsmenisken und einen Perkolationsmechanismus für
                      die Dampfsorption. Darüber hinaus wird eine schnelle und
                      zerstörungsfreie Technik zur Auflösung des
                      Porenradiusverlaufs in PSi eingeführt, der aus
