PERSPECTIVE Correction for “Sliding ferroelectricity in 2D van der Waals materials: Related physics and future opportunities,” by Menghao Wu and Ju Li, which published December 3, 2021; 10.1073/pnas.2115703118 (Proc. Natl. Acad. Sci. U.S.A. 118, e2115703118).
The authors note that a calculation error resulted in overestimated predicted polarizations in Table 2. This error does not affect the conclusions of the article. The corrected Table 2 appears below. The online version has been corrected.
