Journal ArticleDOI
Highly Emissive Divalent Ion Doped Colloidal CsPb1–xMxBr3 Perovskite Nanocrystals through Cation Exchange
Ward van der Stam,Jaco J. Geuchies,Thomas Altantzis,Karel H. W. van den Bos,Johannes D. Meeldijk,Sandra Van Aert,Sara Bals,Daniel Vanmaekelbergh,Celso de Mello Donegá +8 more
TL;DR: This work presents a method that allows partial cation exchange in colloidal CsPbBr3 NCs, whereby Pb2+ is exchanged for several isovalent cations, resulting in doped Cspb1–xMxBr3NCs, with preservation of the original NC shape.
Journal ArticleDOI
Three-dimensional atomic imaging of crystalline nanoparticles
Sandra Van Aert,Kees Joost Batenburg,Kees Joost Batenburg,Marta D. Rossell,Rolf Erni,Gustaaf Van Tendeloo +5 more
TL;DR: 3D reconstruction of a complex crystalline nanoparticle at atomic resolution is reported, which helps close the gap between the atomic resolution achievable in two-dimensional electron micrographs and the coarser resolution that has hitherto been obtained by conventional electron tomography.
Journal ArticleDOI
Smart Align—a new tool for robust non-rigid registration of scanning microscope data
Lewys Jones,Hao Yang,Timothy J. Pennycook,Timothy J. Pennycook,Matthew S. J. Marshall,Sandra Van Aert,Nigel D. Browning,Martin R. Castell,Peter D. Nellist +8 more
TL;DR: In this paper, an improved automated method of performing non-rigid registration customised for the challenges unique to scanned microscope data specifically addressing the issues of low-SNR data, images containing a large proportion of crystalline material and/or local features of interest such as dislocations or edges.
Journal ArticleDOI
Electronically coupled complementary interfaces between perovskite band insulators.
Mark Huijben,Guus Rijnders,Dave H.A. Blank,Sara Bals,Sandra Van Aert,Jo Verbeeck,Gustaaf Van Tendeloo,Alexander Brinkman,Hans Hilgenkamp +8 more
TL;DR: In this paper, a critical separation distance of six perovskite oxides was found, corresponding to approximately 23 A˚, below which a decrease of the interface conductivity and carrier density occurs.
Journal ArticleDOI
Direct Observation of Ferrielectricity at Ferroelastic Domain Boundaries in CaTiO3 by Electron Microscopy
Sandra Van Aert,Stuart Turner,Rémi Delville,Dominique Schryvers,Gustaaf Van Tendeloo,Ekhard K. H. Salje +5 more
TL;DR: This is the first direct observation of the generation of ferroelectricity by interfaces inside this material which opens the door for domain boundary engineering.
