Scientific Reports 6: Article number: 34474; published online: 29 September 2016; updated: 08 May 2017.

As the authors of references 25 and 26 also employed plasma-assisted molecular beam epitaxy for the synthesis of hexagonal boron nitride films, the authors would like to make the following changes to the Introduction section of their Article:

“In addition the direct growth of hBN on a two-dimensional material (HOPG) offers an alternative to chemical vapour deposition23,24,25,26 and atomic layer deposition27 of hBN on metal substrates; this approach must typically be complemented by complex protocols for the removal and transfer of the grown films”.

Should read:
