Simulation of 24,000 Electrons Dynamics: Real-Time Time-Dependent Density Functional Theory (TDDFT) with the Real-Space Multigrids (RMG)
Jacek Jakowski, Wenchang Lu, Emil Briggs +4
We present the theory, implementation, and benchmarking of a real-time time-dependent density functional theory (RT-TDDFT) module within the RMG code, designed to simulate the elec…
Imaging Strain-Localized Single-Photon Emitters in Layered GaSe below the Diffraction Limit
Weijun Luo, Benjamin Lawrie, Alexander Puretzky +6
Nanoscale strain control of exciton funneling is an increasingly critical tool for the scalable production of single photon emitters (SPEs) in two-dimensional materials. However, c…
Photon bunching in cathodoluminescence induced by indirect electron excitation
Vasudevan Iyer, Kevin Roccapriore, Jacob Ng +3
The impulsive excitation of ensembles of excitons or color centers by a high-energy electron beam results in the observation of photon bunching in the second-order correlation func…
QED theory of electron beam-induced electronic excitation and its effect on sputtering cross sections in 2D crystals
Anthony Yoshimura, Michael Lamparski, Joel Giedt +6
Many computational models have been developed to predict the rates of atomic displacements in two-dimensional (2D) materials under electron beam irradiation. However, these models…
Reconstruction of effective potential from statistical analysis of dynamic trajectories
Ali Yousefzadi Nobakht, Ondrej Dyck, David B. Lingerfelt +8
The broad incorporation of microscopic methods is yielding a wealth of information on atomic and mesoscale dynamics of individual atoms, molecules, and particles on surfaces and in…
Direct matter disassembly via electron beam control: Electron-beam-mediated catalytic etching of graphene by nanoparticles
Ondrej Dyck, David Lingerfelt, Songkil Kim +2
We report electron-beam activated motion of a catalytic nanoparticle along a graphene step edge and associated etching of the edge. This approach enables beam-controlled etching of…
