Electron Fourier ptychography for phase reconstruction
Jingjing Zhao, Chen Huang, Ali Mostaed +10
Phase reconstruction is important in transmission electron microscopy for structural studies. We describe electron Fourier ptychography and its application to phase reconstruction…
Identifying Switching of Antiferromagnets by Spin-Orbit Torques
Martin Jourdan, Jonathan Bläßer, Guzmán Orero Gámez +9
Antiferromagnets are promising candidates for ultrafast spintronic applications, leveraging current-induced spin-orbit torques. However, experimentally distinguishing between diffe…
Current-driven writing process in antiferromagnetic Mn2Au for memory applications
Sonka Reimers, Yaryna Lytvynenko, Yuran Niu +9
Current pulse driven Neel vector rotation in metallic antiferromagnets is one of the most promising concepts in antiferromagnetic spintronics. We show microscopically that the Neel…
Nanoscale Chemical Heterogeneity Dominates the Optoelectronic Response over Local Electronic Disorder and Strain in Alloyed Perovskite Solar Cells
Kyle Frohna, Miguel Anaya, Stuart Macpherson +7
Halide perovskites perform remarkably in optoelectronic devices including tandem photovoltaics. However, this exceptional performance is striking given that perovskites exhibit dee…
X-ray Ptychography with a Laboratory Source
Darren J. Batey, Frederic Van Assche, Sander Vanheule +5
X-ray ptychography has revolutionised nanoscale phase contrast imaging at large-scale synchrotron sources in recent years. We present here the first successful demonstration of the…
Quantitative powder diffraction using a (2+3) surface diffractometer and an area detector
Giuseppe Abbondanza, Alfred Larsson, Francesco Carlá +2
X-ray diffractometers primarily designed for surface x-ray diffraction are often used to measure the diffraction from powders, textured materials, and fiber-texture samples in so-c…
