Theory for the mixed alkali effect in glasses
Justus Leiber, Quinn Emilia Fischer, Sven Lohmann +1
The mixed alkali or mixed mobile ion effect in glasses manifests itself by strong nonlinear variations of ionic transport properties upon mixing of different types of mobile ions.…
Universal time-temperature scaling of conductivities in random site energy and associated random barrier model
Sven Lohmann, Quinn Emilia Fischer, Justus Leiber +1
Universal time-temperature scaling of conductivity spectra in disordered solids has been explained by thermally activated hopping of noninteracting particles over random energy bar…
Charge state dynamics of keV ions in solids
Radek Holeňák, Kevin Vomschee, Eleni Ntemou +2
Fast dynamic processes between electrons in solids and a foreign atom represent a fundamental challenge for describing interactions in many-body systems and are a prerequisite for…
Contrast modes in a 3D ion transmission approach at keV energies
R. Holeňák, S. Lohmann, D. Primetzhofer
We present options for visualizing contrast maps in 3D ion transmission experiments. Simultaneous measurement of angular distributions and flight time of ions transmitted through s…
Assessing electron emission induced by pulsed ion beams: a time-of-flight approach
Svenja Lohmann, Anna Niggas, Vincent Charnay +2
We present a method to measure the kinetic energy of electrons emitted upon ion impact via their time-of-flight. Pulsed beams of H, D, He and Ne ions with…
Disparate energy scaling of trajectory-dependent electronic excitations for slow protons and He ions
Svenja Lohmann, Daniel Primetzhofer
We have simultaneously measured angular distributions and electronic energy loss of helium ions and protons directly transmitted through self-supporting, single-crystalline silicon…
