Trajectory dependence of electronic energy-loss straggling at keV ion energies
Svenja Lohmann, Radek Holeňák, Pedro L. Grande +1
We have measured the electronic energy-loss straggling of protons, helium, boron and silicon ions in silicon using a transmission time-of-flight approach. Ions with velocities betw…
Time-of-flight recoil detection in transmission using pulsed keV ion beams enables sensitive multi-element profiling with high depth resolution
R. Holeňák, S. Lohmann, D. Primetzhofer
The potential of time-of-flight recoil detection in transmission geometry using pulsed keV ion beams for sensitive multi-element profiling of thin membranes and quasi-2D systems is…
On the correlation of angular distributions of keV ions and trajectory-dependent electronic excitations in transmission channelling geometry
Radek Holeňák, Svenja Lohmann, Kristina Komander +1
We use energy discrimination of keV ions transmitted through a thin, single-crystalline silicon membrane to correlate specific angular distribution patterns formed in channelling g…
Simultaneous assessment of energy, charge state and angular distribution for medium energy ions interacting with ultra-thin self-supporting targets: a time-of-flight approach
R. Holeňák, S. Lohmann, F. Sekula +1
We demonstrate simultaneous measurements of the charge state, energy and angular distribution of keV ions in transmission experiments through self-supporting foils. Using a time-of…
Influence of interface-driven strain on the spectral diffusion properties of core/shell CdSe/CdS dot/rod nanoparticles
Sven-Hendrik Lohmann, Philip Harder, Felix Bourier +3
By combining an atomistic valence-force field approach and calculations based on the effective-mass approximation we investigate the influence of strain effects on the band alignme…
Surface Charges on CdSe-Dot/CdS-Rod Nanocrystals: Measuring and Modeling the Diffusion of Exciton-Fluorescence Rates and Energies
Sven-Hendrik Lohmann, Christian Strelow, Alf Mews +1
By performing spectroscopic single-particle measurements at cryogenic temperatures over the course of hours we study %By performing spectroscopic longtime single-particle measureme…
Radiative rotational lifetimes and state-resolved relative detachment cross sections from photodetachment thermometry of molecular anions in a cryogenic storage ring
C. Meyer, A. Becker, K. Blaum +23
Photodetachment thermometry on a beam of OH in a cryogenic storage ring cooled to below 10 K is carried out using two-dimensional, frequency and time dependent photodetachment…
