Universidad de Zaragoza (orcid)0000-0002-9102-7895 Aberration-corrected transmission electron microscopy with Zernike phase plates 2022 Access copy available to the general public Unrestricted We explore the possibility of applying physical phase plates (PPs) in combination with aberration-corrected transmission electron microscopy. Phase-contrast transfer characteristics are calculated and compared for a thin-film based Zernike PP, a hole-free (HF) or Volta PP and an electrostatic Zach PP, considering their phase-shifting properties in combination with partial spatial coherence. The effect of slightly converging illumination conditions, often used in high-resolution applications, on imaging with PPs is discussed. Experiments with an unheated Zernike PP applied to various nanomaterial specimens and a qualitative analysis clearly demonstrates the general compatibility of PPs and aberration-corrected transmission electron microscopy. Calculations and experiments show the benefits of the approach, among which is a strong phase-contrast enhancement of a large range of spatial frequencies. This allows the simultaneous imaging of atomic-resolution structures and morphological features at the nanometer scale, with maximum phase contrast. The calculations can explain why the HFPP damps contrast transfer at higher spatial frequencies. © 2022 The Author(s) info:eu-repo/grantAgreement/ES/DGA/E13-20R info:eu-repo/grantAgreement/EC/H2020/823717/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM3 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823717-ESTEEM3 info:eu-repo/grantAgreement/EC/H2020/881603/EU/Graphene Flagship Core Project 3/GrapheneCore3 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 881603-GrapheneCore3 info:eu-repo/grantAgreement/EC/H2020/889546/EU/Properties of nanomaterials made from misfit-layered compounds revealed by electron microscopy and simulations/PROMISES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 889546-PROMISES info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/PID2019-104739GB-I00-AEI-10.13039-501100011033 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.2 2022 MICROSCOPY 5 / 8 = 0.625 2022 Q3 T2 0.794 2022 Atomic and Molecular Physics, and Optics 2022 Q1 Instrumentation 2022 Q1 Electronic, Optical and Magnetic Materials 2022 Q1 5.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Arenal, R. 2003 395 Universidad de Zaragoza Dpto.
