Correction to: Nature Materials https://doi.org/10.1038/s41563-020-0732-6, published online 13 July 2020.

In the version of this Article originally published, the following sentence was missing from the Acknowledgements section: ‘Work at Auburn University was supported by the Auburn University Intramural Grants Program and the National Science Foundation under grant no. DMR-2005194.’ It should have followed the first sentence of the Acknowledgements. This has now been corrected in all versions of the Article.
