We very much regret the following inaccuracy in our original paper: The set of InN nanocolumn samples discussed in the article was not grown using Au as a catalyst. Instead, the growth was performed catalystfree by plasma-assisted molecular beam epitaxy. While the results and conclusions presented in the article should not be affected by the erroneous description of the growth procedure, we would like to avoid any possible confusion in the nanowire growth community. To our knowledge, there has been no report about the growth of InN nanowires using Au as a catalyst so far. Moreover, the growth mode of catalyst-free InN nanowires has been debated, but could not be clarified indubitably. However, it is very likely that it is not a vapour-liquid-solid type of growth. Furthermore, there is an ongoing discussion to which extend the structural and optical properties of nanowires are influenced by the use of a catalyst droplet (e.g. Ni for the case of InN nanowires). For GaN nanowires, this has been discussed for example by Cheze et al. [1]. In this context we would like to stress again, that the optical properties discussed in the paper refer to catalyst-free InN nanowires.
