Correction to “Persistent Energetic Electrons in Methylammonium Lead Iodide Perovskite Thin Films” Daniel Niesner, Haiming Zhu, Kiyoshi Miyata, Prakriti P. Joshi, Tyler J. S. Evans, Bryan J. Kudisch, M. Tuan Trinh, Manuel Marks, and X.-Y. Zhu* J. Am. Chem. Soc. 2016, 138, 15717−15726. DOI: 10.1021/jacs.6b08880 Page 15718. In Figure 1A, the energy of the photoelectrons (yaxis) was wrongly labeled as −0.6 to 0 eV. The correct label is −6 to 0 eV, as shown in the corrected Figure 1:
Figure 1. Valence band structure from photoemission. (A) 2D gray scale (intensity) of ARPES (hν = 21.2 eV) from CH3NH3PbI3/SiO2. Intensity in the blue box is multiplied by a factor of 5. The orange curves are reproduced from band structure calculations in ref 22. (B) Angle-integrated spectrum (gray curve) in the valence region, along with a two-photon photoemission spectrum (blue, hν1 = 2.68 eV; hν2 = 4.43 eV). (C) Schematics of one photon photoemission spectroscopy (UPS, hν = 21.2 eV) and two-photon photoemission spectroscopy (2PPE).
