The originally published article contained some wrongly numbered references. In the first paragraph of the “Atomically thin 2D membranes” section, the original text read “There are two dominant methods used for fabricating free-standing 2D membranes: transfer of a 2D material prepared by exfoliation110,111 or CVD80,98,99,103,104,105,106,109 on a membrane with a relatively large sub-micrometre aperture (Fig. 1h); or growth of the 2D material directly on the aperture using CVD100,108,112 (Fig. 1i). The first method is more common, as the procedures for material transfer are well established and the system is easy to inspect optically113. Direct CVD grown on the aperture is scalable to whole wafers112, but the process is challenging to control.” The correct references in this paragraph are “There are two dominant methods used for fabricating free-standing 2D membranes: transfer of a 2D material prepared by exfoliation110,111 or CVD80,98,99,103,104,105,106,109,112 on a membrane with a relatively large sub-micrometre aperture (Fig. 1h); or growth of the 2D material directly on the aperture using CVD100,108 (Fig. 1i).
