In the version of this article originally published, the substrate used in reference 111 to grow InAs/GaAs quantum dots was silicon. However, theauthors have found out that 500 nm of germanium was first grown on silicon by chemical vapor deposition before growing InAs/GaAs quantumdots. Therefore, the InAs/GaAs quantum dots reported in reference 111 are actually grown on Ge-on-Si substrate. Therefore
