Correction to: Nature Nanotechnology https://doi.org/10.1038/s41565-021-00883-7, published online 22 April 2021.

In the version of article initially published, there was an error in the Acknowledgements section, which has been corrected, in part, to read “…the grant (R-263-000-E55-305) from A*STAR under the Advanced Manufacturing and Engineering (AME) Individual Research Grant (IRG), under no. A2083c0060.” The changes have been made to the HTML and PDF versions of the article.
