Autor: Amir H. Tavabi, Hugo Larocque, Peng-Han Lu, Martial Duchamp, Vincenzo Grillo, Ebrahim Karimi, Rafal E. Dunin-Borkowski, Giulio Pozzi

Publikováno v: Physical Review Research, Vol 2, Iss 1, p 013185 (2020)

Vortices in electron beams can manifest several types of topological phenomena, such as the formation of exotic structures or interactions with topologically structured electromagnetic fields. For instance, the wave function of an electron beam can a

Nanoscale Three-Dimensional Charge Density and Electric Field Mapping by Electron Holographic Tomography

Autor: Fengshan Zheng, Vadim Migunov, Jan Caron, Hongchu Du, Giulio Pozzi, Rafal E. Dunin-Borkowski

Publikováno v: Nano letters 23(3), 843-849 (2023). doi:10.1021/acs.nanolett.2c03879

The operation of nanoscale electronic devices is related intimately to the three-dimensional (3D) charge density distributions within them. Here, we demonstrate the quantitative 3D mapping of the charge density and long-range electric field associate

Publikováno v: Ultramicroscopy. 241

Electrostatic charging of specimens during electron, photon or ion irradiation is a complicated and poorly understood phenomenon, which can affect the acquisition and interpretation of experimental data and alter the functional properties of the cons

The orbital angular momentum (OAM) sorter is an electron optical device for the measurement of an electron's OAM. It is based on two phase elements, which are referred to as an ''unwrapper'' and a ''corrector'' and are located in Fourier conjugate pl

Publikováno v: Nanoscale. 12(19)

We use an electron holographic method to determine the charge distribution along a quasi-one-dimensional W5O14 nanowire during in situ field emission in a transmission electron microscope. The results show that the continuous charge distribution alon
