      abstract     = {In this work, we report on how to obtain site- and
                      size-controlled InN quantum dots (QDs) by selective area
                      metalorganic vapour phase epitaxy (SA-MOVPE) and how to
                      embed them into a vertical p-n junction for future single
                      photon emitters. To this purpose we investigated the growth
                      of InN nanostructures in differently sized mask apertures as
                      a function of the growth time and established a low
                      temperature growth process to cover these structures with a
                      p-doped GaN cap layer. We observed that single sub-25 nm
                      quantum dots can be achieved when the aperture diameter is
                      reduced to 20 nm and the growth time accounts for less than
                      a minute. Micro-photoluminescence (μ-PL) measurements on
                      single GaN capped InN nano-pyramids exhibit a broad and
                      intense DAP transition band in the range of 2.85 eV
                      indicating successful p-doping.},
