Hall mobilities and sheet carrier densities in a single LiNbO conductive ferroelectric domain wall
Henrik Beccard, Elke Beyreuther, Benjamin Kirbus +3
For the last decade, conductive domain walls (CDWs) in single crystals of the uniaxial model ferroelectric lithium niobate (LiNbO, LNO) have shown to reach resistances more tha…
R2D2 -- An equivalent-circuit model that quantitatively describes domain wall conductivity in ferroelectric LiNbO
Manuel Zahn, Elke Beyreuther, Iuliia Kiseleva +7
Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two separate mechanisms: (a) the injection/ejection of charge carriers across the Schottky barrier formed at…
Large Hall electron mobilities in head-to-head BaTiO-domain walls
Henrik Beccard, Benjamin Kirbus, Elke Beyreuther +4
Strongly charged head-to-head (H2H) domain walls (DWs) that are purposely engineered along the [110] crystallographic orientation into ferroelectric BaTiO single crystals have…
Does FLASH deplete Oxygen? Experimental Evaluation for Photons, Protons and Carbon Ions
Jeannette Jansen, Jan Knoll, Elke Beyreuther +6
Purpose: To investigate experimentally, if FLASH irradiation depletes oxygen within water for different radiation types such as photons, protons and carbon ions. Methods: This stud…
Optical-Field Driven Charge-Transfer Modulations near Composite Nanostructures
Kwang Jin Lee, Elke Beyreuther, Sohail A. Jalil +4
Optical activation of material properties illustrates the potentials held by tuning light-matter interactions with impacts ranging from basic science to technological applications.…
Spectral and spatial shaping of laser-driven proton beams using a pulsed high-field magnet beamline
Florian-Emanuel Brack, Florian Kroll, Lennart Gaus +17
Intense laser-driven proton pulses, inherently broadband and highly divergent, pose a challenge to established beamline concepts on the path to application-adapted irradiation fiel…
Electrical-transport characteristics of as-grown and oxygen-reduced LaCeMnO films: calculation of hopping energies, Mn valences, and carrier localization lengths
Andreas Thiessen, Elke Beyreuther, Robert Werner +3
Presently, cerium-doped LaMnO is vividly discussed as an electron-doped counterpart prototype to the well-established hole-doped mixed-valence manganites. Here, LaCe$_{…
Conducting and insulating LaAlO/SrTiO interfaces: A comparative surface photovoltage investigation
Elke Beyreuther, Domenico Paparo, Andreas Thiessen +2
Surface photovoltage (SPV) spectroscopy, which is a versatile method to analyze the energetic distribution of electronic defect states at surfaces and interfaces of wide-bandgap se…
