AB - 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
AB - 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.
