Correction to: Nature Electronics https://doi.org/10.1038/s41928-021-00561-5, published online 5 April 2021.

In the version of this Article originally published, in the Author Contributions section the text that read ‘A.Z. and P.A. synthesized the chalcogen mixture and developed the synthesis procedure for 2D β-TeO2 while also conducting XPS, Raman and AFM measurements. B.Y.Z. conducted some AFM imaging and contributed to low-temperature device testing’ was incorrect; it should have read: ‘A.Z. and P.A. synthesized the chalcogen mixture and developed the synthesis procedure for 2D β-TeO2 while also conducting XPS and Raman measurements. A.Z., P.A. and B.Y.Z. performed the AFM imaging.’ This has now been corrected.
