Mesoscopic structures in liquids have an impact on the diffusion dynamics of the constituting
molecules. Smectic 8CB liquid crystals on silicon wafers show the formation of mesoscopic …

Spectral diffusion as a result of both the transitions between different molecular conformers
and the′′ molecular softness′′ of quasi‐free perylene diimides on a SiO2 surface is …

Heterogeneous line broadening and spectral diffusion of the fluorescence emission spectra
of perylene diimide molecules have been investigated by means of time dependent single …

Lateral diffusion of three different dye molecules (terrylene and two perylene diimides) in 4
to 225 nm thin films of 8CB liquid crystals in the smectic-A phase has been investigated on a …

Single molecule tracer diffusion studies of evaporating (thinning) ultrathin tetrakis-2-ethyl-
hexoxysilane (TEHOS) films on silicon with 100 nm thermal oxide reveal a considerable …

The aim of this thesis is to investigate the influence of the stochastic interpretation of the
Langevin equation with state-dependent diffusion coefficient on the propagator of the related …

Diffusion is a widely occurring phenomenon in the world surrounding us. Whether we look at
astrophysics, environmentalism, biology, sociology and also in various technical …

The results presented in this thesis have been stimulated within the framework of the VW-
