Floquet theory of electronic stopping processes of projectiles in solids
… a new theoretical framework for the study of electronic stopping of particle projectiles in crystalline solids. It does not rely on perturbative or linear response approximations. Moreover, it goes beyond nonlinear models for the homogeneous electron gas, which assume ideal metal hosts. The …

On the prediction of electronic stopping power from first principles
The prediction of electronic stopping power in materials from first principles using real-time time-dependent density functional theory, as implemented in the SIESTA code, combines classical motion of the nuclei with evolution of the electronic wavefunctions according to the time-dependent …

Non-adiabatic electron-ion dynamics in semiconductors under ionizing particle irradiation
… slowed down differently at different velocities: Electronic stopping dominates at high velocity while nuclear stopping prevails at low velocity. The elastic collisions between slow ions and target materials were well-studied in the past. However, how energetic ions interact with target materials, …

Sub-10-nm lithography with light-ion beams
… as directly proportional to the so-called stopping power of incident beam particles - i.e. the average energy loss per unit path length, particularly for thin (less than 20 nm thick) resist. Values of stopping power are readily obtained via the popular Stopping and Range of Ions in Matter …

Molecular dynamic simulation of xenon bubble re-solution in uranium dioxide
… re-solution of Xenon fission gas bubbles due to electronic energy deposition of fission fragments is investigated using MD simulations. First, a two-temperature model (TTM) coupling the electronic (e-) and phonon (p-) system is employed to determine the temperature profile along the tracks of …

Effects of vacancies and electron temperature on the electron phonon coupling in cubic silicon carbide and their connection to the inelastic thermal spike
… coupling is found to depend strongly on the electronic temperature and on the presence of vacancies. Electron-phonon mean free paths were calculated to explore the possibility of extending those calculations to lower vacancy concentrations using a rule-of-mixtures approach. </p><p>The …

Extending the dielectric formalism in warm dense matter: collisions, dynamic structure factors, and stopping powers
… material properties like transport coefficients, stopping powers, scattering and absorption spectra, and many other quantities in the WDM regime. However, competing physical effects, like partial ionization, correlated ion behavior, and quantum degeneracy makes model- ing WDM challenging and often …
