Publisher Correction: Quantum engineering of transistors based on 2D materials heterostructures.

In the version of this Perspective originally published, in the email address for the author Giuseppe Iannaccone, the surname was incorrectly given as "innaconne"; this has now been corrected in all versions of the Perspective. Also, an error in the production process led to Figs. 1, 2 and 3 being of low resolution; these have now been replaced with higher-quality versions.
