      abstract     = {The success of future organic electronic devices
                      distinctively depends on the electronic and geometric
                      properties of thin organic films. Although obviously these
                      properties are strongly influenced by the growth mechanisms,
                      real time growth studies are relatively rare since not many
                      experimental techniques exist that allow in situ studies in
                      ultra high vacuum. In this context, we investigated the
                      prototypical system
                      1,4,5,8-naphtalene-tetracarboxylic-dianhydride (NTCDA) on
                      Cu(001). We used low-energy electron microscopy (LEEM) for
                      the real-time growth study, and a variety of other
                      techniques for investigating the geometric and electronic
                      structure. While for similar model systems well known and
                      well characterized growth modi occur (e.g., compact, well
                      ordered islands or disordered, gas-like layers), for
                      NTCDA/Cu(001) we observe the growth of dendrite-like,
                      fractal structures. The dendritic structures arise from a
                      strongly preferred one-dimensional growth mode forming a
                      long-range ordered network of thin molecular chains spanning
                      over the entire surface already at small coverages. Later in
                      the growth process, the voids in the network structure are
                      incrementally filled. These results are very unexpected for
                      such a simple adsorbate system consisting of well
                      investigated components, the properties of which were
                      believed to be already well understood. We explain this
                      unexpected behavior by a dendritic growth model that is
                      supported by energetic arguments based on pair-potential
                      calculations. These calculations give reason for the
                      experimentally observed growth of one-dimensional
                      structures, and therefore represent the key to a
                      semi-quantitative understanding of this dendritic growth
                      mode.},
