Nature of the positron state in CdSe quantum dots
Wenqin Shi, Vincent Callewaert, Bernardo Barbiellini +11
Previous studies have shown that positron-annihilation spectroscopy is a highly sensitive probe of the electronic structure and surface composition of ligand-capped semiconductor Q…
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…
In-situ observation of temperature-dependent segregation of Ni adatoms on oriented Pd surfaces
Samantha Zimnik, Marcel Dickmann, Christoph Hugenschmidt
We report the direct observation of the in-situ temperature-dependent surface segregation of Ni adatoms on single crystalline Pd surfaces using Positron annihilation induced Auger…
