Updated all-electron Dirac--Fock densities and an element-adaptive parameterisation of scattering factors and potentials for neutral atoms
Ivan Lobato, Zezhong Zhang, Sandra Van Aert +1
Updated reference data and an analytic parameterisation of elastic electron and X-ray scattering are presented for all 118 neutral atoms. The reference electron densities for the m…
Detective Quantum Efficiency of the Timepix4 Hybrid Pixel Detector and its Application to Parallel-Beam Diffraction
Zhiyuan Ding, Nina Dimova, Jonathan S. Barnard +6
The detective quantum efficiency (DQE) and normalised noise power spectrum (NNPS) of the Timepix4 hybrid pixel detector in event-driven mode in TEM have been measured at 100 kV and…
Physics-Informed 3D Atomic Reconstruction and Dynamics of Free-Standing Graphene from Single Low-Dose TEM Images
Xiaojun Zhang, Shih-Wei Hung, Yawei Wu +4
Resolving the three-dimensional (3D) atomic geometry of free-standing graphene in real time is essential for understanding how intrinsic rippling governs its electronic properties.…
Atomic resolution imaging of the strength and 3D direction of atomic displacements in functional oxide thin films
Ian MacLaren, Aurys Silinga, Juri Barthel +4
Atomic resolution imaging is key to understanding thin film growth and how a particular set of conditions influences properties. Whilst such imaging in the scanning transmission el…
