Muonium dynamics as a probe for depth-resolved properties of 4H-SiC
Maria Mendes Martins, Piyush Kumar, Marianne E. Bathen +5
This study establishes a baseline for muonium (Mu) charge-exchange dynamics in n-type 4H-SiC through a detailed low-energy muon spin rotation (LE-uSR) investigation. Epitaxially gr…

Observation and manipulation of charge carrier distribution at the SiO/Si interface
Maria M. Martins, Piyush Kumar, Marianne E. Bathen +3
Using low-energy muons, we map the charge carrier concentration as a function of depth and electric field across the \SiOSi interface up to a depth of \SI{100}{\nano\meter} in Si-b…

Improving the low-energy muon beam quality of the LEM beamline at PSI: Characterisation of ultra-thin carbon foils
Gianluca Janka, Maria Mendes Martins, Xiaojie Ni +3
The Low-Energy Muon beamline (LEM) at the Paul Scherrer Institute currently stands as the world's only facility providing a continuous beam of low-energy muons with keV energies fo…
