The Origin of Enhanced Conductivity and Structure Change in Defective Li4Ti5O12 or Blue-LTO : a study combined theoretical and experimental perspectives
Yute Chan, Cristina Grosu, Matthias Kick +8
The spinel Li4Ti5O12 (LTO) has emerged as a promising anode material for the next generation of all-solid-state Li-ion batteries (ASSB), primarily due to its characteristic "zero s…
Absolute fraction of emitted Ps determined by GEANT4 supported analysis of gamma spectra
Benjamin Rienäcker, Thomas Gigl, Giancarlo Nebbia +2
The fraction of positronium (Ps) emitted from a surface of a germanium single crystal at high temperature is usually assumed to approach unity at zero positron implantation energy.…
Breakdown of the Arrhenius Law of the Temperature Dependent Vacancy Concentration in fcc-Lanthanum
Lucian Mathes, Thomas Gigl, Michael Leitner +1
We measured the temperature dependent equilibrium vacancy concentration using in-situ positron annihilation spectroscopy in order to determine the enthalpy and entropy…
Impact of Oxygen Diffusion on Superconductivity in YBaCuO Thin Films Studied by Positron Annihilation Spectroscopy
M. Reiner, T. Gigl, R. Jany +2
The oxygen deficiency in YBaCuO (YBCO) plays a crucial role for affecting high-temperature superconductivity. We applied (coincident) Doppler broadening spectro…
Defect Imaging and Detection of Precipitates Using a New Scanning Positron Microbeam
Thomas Gigl, Lukas Beddrich, Marcel Dickmann +4
We report on a newly developed scanning positron microbeam based on threefold moderation of positrons provided by the high intensity positron source NEPOMUC. For brightness enhance…
Positron spectroscopy of point defects in the skyrmion-lattice compound MnSi
Markus Reiner, Andreas Bauer, Michael Leitner +7
Outstanding crystalline perfection is a key requirement for the formation of new forms of electronic order in a vast number of widely different materials. Whereas excellent sample…
Detection and imaging of the oxygen deficiency in single crystalline YBaCuO thin films using a positron beam
Markus Reiner, Thomas Gigl, Rainer Jany +2
Single crystalline YBaCuO (YBCO) thin films were grown by pulsed laser deposition (PLD) in order to probe the oxygen deficiency using a…
Quality of Heusler Single Crystals Examined by Depth Dependent Positron Annihilation Techniques
C Hugenschmidt, A Bauer, P Böni +9
Heusler compounds exhibit a wide range of different electronic ground states and are hence expected to be applicable as functional materials in novel electronic and spintronic devi…
