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

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
