      abstract     = {Strontium cobaltite (SrCoO$_{3-\delta}$) exists in two
                      topotactic phases, depending on the oxygen content.
                      SrCoO$_3$ is a ferromagnetic metal (T$_C$ =305K) with
                      perovskite structure while SrCoO$_{2.5}$ is an
                      antiferromagnetic insulator (T$_N$ =570K) with
                      brownmillerite tructure [1]. We aim at growing thin films of
                      SrCoO$_{3−\delta}$ via molecular beam epitaxy, and thus
                      investigate the influence of growth conditions like the
                      elemental deposition rate of Sr and Co, substrate
                      temperature and oxygen pressure on the sample toichiometry
                      and surface topography. For this, we employ in-situ electron
                      diffraction to monitor the sample growth and ex-situ X-ray
                      reflectometry and atomic force microscopy to investigate the
                      structural properties. The stoichiometry is determined by
                      Rutherford backscattering spectrometry. We provide a
                      comprehensive overview of the samples addressing the
                      requirements to achieve a Sr:Co stoichiometry of 1:1.
