Detection of light emission produced in the process of positronium formation
M. Pietrow, R. Zaleski, A. Wagner +6
The excess energy emitted during the positronium (Ps) formation in condensed matter may be released as light. Spectroscopic analysis of this light can be a new method of studying t…
Dissolution of donor-vacancy clusters in heavily doped n-type germanium
Slawomir Prucnal, Maciej O. Liedke, Xiaoshuang Wang +17
The n-type doping of Ge is a self-limiting process due to the formation of vacancy-donor complexes (DnV with n <= 4) that deactivate the donors. This work unambiguously demonstrate…
Mapping the Structure of Oxygen-Doped Wurtzite Aluminum Nitride Coatings From Ab Initio Random Structure Search and Experiments
Piero Gasparotto, Maria Fischer, Daniele Scopece +8
Machine learning is changing how we design and interpret experiments in materials science. In this work, we show how unsupervised learning, combined with ab initio modeling, improv…
Vacancy-Hydrogen Interaction in Niobium during Low-Temperature Baking
Marc Wenskat, Jakub Cizek, Maciej Oskar Liedke +6
A recently discovered modified low-temperature baking leads to reduced surface losses and an increase of the accelerating gradient of superconducting TESLA shape cavities. We will…
Nitrogen magneto-ionics
Julius de Rojas, Alberto Quintana, Aitor Lopeandía +15
So far, magneto-ionics, understood as voltage-driven ion transport in magnetic materials, has largely relied on controlled migration of oxygen ion/vacancy and, to a lesser extent,…
Boosting room temperature magneto-ionics in Co3O4
Julius de Rojas, Alberto Quintana, Aitor Lopeandía +11
Voltage control of magnetism through electric field-induced oxygen motion (magneto-ionics) could represent a significant breakthrough in the pursuit for new strategies to enhance e…
